Аннотация: This paper reports on first results of the synthesis and study of the thermal, structural, electrical, resonance, and magnetic properties of new sulfide materials Mex Mn1 – S (Me = Cu, 0 ˂ x ˂ 0.2) synthesized based on manganese monosulfide. The materials have a NaCl cubic structure at 300 K and undergo a con centration metal–insulator transition with increasing degree of substitution and with varying temperature. The magnetic transition occurs in the region of the heat capacity anomaly. The Néel temperature is slightly dependent on the copper concentration. The samples with a high copper content exhibit metallic conduction at T ˂ 260 K and semiconductor conduction at T ˃ 260 K.

Transition metal oxyborate -- Distinct crystallographic position -- Spin glass magnetic ordering
Аннотация: The needle shape single crystals Co3−x MnxO2BO3 with ludwigite structure have been prepared. According to the X-ray diffraction data the preferable character of distinct crystallographic positions occupation by Mn ions is established. Magnetization field and temperature dependencies are measured. Paramagnetic Curie temperature value Θ=−100 K points out the predominance of antiferromagnetic interactions. Spin-glass magnetic ordering takes the onset at TN=41 K. The crystallographic and magnetic properties of Co3O2BO3:Mn are compared with the same for the isostructural analogs Co3O2BO3 and CoO2BO3:Fe.

Аннотация: Reactions of Fe-2(CO)(9) with Cp(CO)(2)Mn=C=CHPh (1) and Cp(CO)(PPh3)Mn=C=CHPh (3) gave the heterometallic trimethylenemethane complexes eta(4)-{C[Mn(CO)(2)Cp](CO)CHPh}Fe(CO)(3) (2) and eta(4)-{C[Mn(CO)(PPh3)Cp](CO)CHPh}Fe(CO)(3) (4), respectively. The formation of the benzylideneketene [PhHC=C=C=O] fragment included in complexes 2 and 4 occurs via intramolecular coupling of the carbonyl and vinylidene ligands. The structures of 3 and 4 were determined by single crystal XRD methods. The influence of the nature of the L ligands at the Mn atom on the structural and spectroscopic characteristics of eta(4)-{C[Mn(CO)(L)Cp](CO)CHPh}Fe(CO)(3) (L = CO (2), PPh3 (4)) is considered. According to the VT H-1 and C-13 NMR spectra, complex 2 reversibly transforms in solution into mu-eta(1):eta(1)-vinylidene isomer Cp(CO)(2)MnFe(mu-C=CHPh)(CO)(4) (2a), whereas complex 4 containing the PPh3 ligand is not able to a similar transformation.

Аннотация: The structural, magnetic, and thermophysical properties of cation-substituted sulfides GdXMn1-XS (0.04 ? X ? 0.25) with the NaCl-type face-centered cubic lattice have been investigated. The range of existence of long-range antiferromagnetic order has been established. The anomalies observed in the temperature dependence of the specific heat correspond to the temperatures of the magnetic phase transition. The anomaly in the specific heat caused by electron transitions between the 4f levels and d band states has been observed. It has been found that the coefficient of thermal expansion decreases with increasing concentration of substituents in the magnetically ordered region and remains nearly invariable in the paramagnetic phase.

Magnetic properties and morphology of manganese ferrite nanoparticles in glasses / I. Edelman [et al.] // IOP Conf. Ser.: Mater. Sci. Eng. - 2011. - Vol. 25, Is. 1. - Ст. 012017, DOI 10.1088/1757-899X/25/1/012017

Аннотация: Static magnetization (SM), magnetic circular dichroism (MCD) and electron magnetic resonance (EMR) studies are reported of borate glasses 22.5 K 2O-22.5 Al 2O 3-55 B 2O 3 co-doped with iron and manganese oxides. In as-prepared glasses the paramagnetic ions usually are in diluted state; however, if the ratio of the iron and manganese oxides in the charge is 3/2, magnetic nanoparticles are found already in as-prepared glass. After additional thermal treatment all glasses show magnetic behaviour, MCD and EMR due to the presence of magnetic nanoparticles with characteristics close to those of manganese ferrite. By computer simulating the EMR spectra at variable temperatures, their morphological characteristics are deduced: relatively broad size and shape distribution with average diameter of ca. 3-4 nm. The characteristic temperature-dependent shift of the apparent resonance field is explained by a strong temperature dependence of the magnetocrystalline anisotropy in the nanoparticles. The potassium-alumina-borate glasses containing magnetic nanoparticles represent a novel class of materials: "transparent magnets". Indeed, they remain transparent in a part of visible and near infrared spectral range while showing magnetic and magneto-optical properties characteristic of magnetically ordered materials.

Аннотация: The behaviour of the optical absorption bands of NaMnCl//3 is experimentally studied in the region of the **6A//1//g to **4A//1//g, **4E//g(**4G) transition of the Mn**2** plus ion in the temperature range 1. 8 to 20 K and in magnetic fields up to 20 T. Exciton and its 'hot' magnon sidebands are observed in the spectrum. The anomalous temperature dependence of the exciton-magnon bands intensity is explained by participation of magnons with wave vector K does not equal 0 in absorption. The low energy exciton-magnon band is supposed to be due to simultaneous creation of an exciton and annihilation of three thermally created magnons.

Аннотация: We demonstrate that a magnetic tunnel structure irradiated by microwaves can generate a significant voltage signal due to the rectification effect. The measurements were carried out using current-in-plane geometry with a current flowing parallel to the interfaces in the structure. A value of the microwave-induced voltage strongly depends on a bias current and can be driven by a magnetic field. The rectification effect is discussed both in "Classical" terms of nonlinearity of the current-voltage characteristic and using a mechanism that involves the interplay between the spinpolarized current and magnetization dynamics in the magnetic tunnel structure.

Characterization of manganese and iron silicides by in situ spectral generalized magneto-optical ellipsometry / N. N. Kosyrev [et al.] // 7th Workshop on Ellipsometry : abstract book. - 2012. - P. . - 82
Аннотация: Dilute magnetic semiconductors (DMS) combine the electronic transport properties of semiconductors and memory characteristics of magnetic materials. The complementary properties of semiconductor and ferromagnetic material can manipulate both degrees of freedoms of electrons0 spins and charges for spintronic devices. In recent years, group IV(Ge,Si)-based DMSs attract considerable experimental effort due to the compatibility with mainstream silicon technology. In ourworkwe present the investigation of structural,magnetic and optical properties ofmanganese and iron silicides thin films on Si (100) substrate by in situ spectral generalizedmagneto-optical ellipsometry. Themeasurementswere performed by spectral and laser ellipsometers (“Spectroscan“ and “LEF-71“ respectively by Institute Semiconductors Physics SB RAS), optimized tomeasure not only traditional ellipsometric parameters, but also magneto-optical response of the sample. The magnetoellipsometers were integrated into the ultrahigh vacuum chambers of molecular beam epitaxy setup, which allowed to control the optical and magnetic properties of thin films directly in the growth process. As a result of the magneto-optical response analysis, it was found that iron and manganese silicides in magnetic phase were formed on the Si surface and by analysis of the ellipsometric parameters dependence on evaporation time the silicide nanoclusters were identified and their structural properties were found. The work was supported by project 4.1 of the OFN RAS, project 27.10 of the Presidium RAS, integration project22 of SB RAS and FEB RAS, and also the FCP NK-744P/6 .

Аннотация: Initial growth stages of manganese films on the Si(100)2 × 1 surface at room temperature have been investigated using high-energy-resolution photoelectron spectroscopy, and the dynamics of the variation in their phase composition and electronic structure with the coverage growth has been revealed. It has been shown that the interfacial manganese silicide and the film of the solid solution of silicon in manganese are sequentially formed under these conditions on the silicon surface. The growth of the metal manganese film starts after the deposition of ~0.9 nm Mn. Segregation of silicon on the film surface is observed in the range of coverages up to 1.6 nm Mn.

Аннотация: The results of X-ray diffraction (XRD) structural investigations of Pb3Mn7O15 crystals carried out for a wide temperature range including the room temperature are presented. It has been observed for the first time that with increasing temperature the Pb3Mn7O15 crystals transform from the orthorhombic (Pnma space group) to the hexagonal (P6(3)/mcm space group) structure. The results of the thermal analysis have revealed two sharp peaks in the temperature dependence correlating with the XRD data. According to the results of the group-theoretical analysis, the Pb3Mn7O15 symmetry transformation can be described as P6(3)/mcm M-2(-)(12-4)(eta,0,0) over right arrow Pnma. (C) 2011 Elsevier B.V.

Аннотация: The solid-phase synthesis of manganese silicides on the Si(100)2 × 1 surface coated at room temperature by a 2-nm-thick manganese film has been investigated using high-energy-resolution photoelectron spectroscopy with synchrotron radiation. The dynamics of variation of the phase composition and electronic structure of the near-surface region with increasing sample annealing temperature to 600°C, has been revealed. It has been shown that, under these conditions, a solid solution of silicon in manganese, metallic manganese monosilicide MnSi, and semiconductor silicide MnSi1.7 are successively formed on the silicon surface. The films of both silicides are not continuous, with the fraction of the substrate surface occupied by them decreasing with increasing annealing temperature. The binding energies of the Si 2p and Mn 3p electrons in the compounds synthesized have been determined.

Synthesis of ferromagnetic germanides in 40Ge/60Mn films: Magnetic and structural properties / V. G. Myagkov [et al.] // Solid State Phenom. : Selected, peer reviewed papers. - 2014. - Vol. 215: Trends in Magnetism: Nanomagnetism (EASTMAG-2013). - P. 167-172, DOI 10.4028/www.scientific.net/SSP.215.167. - Cited References: 28 . - ISSN 978-30383. - ISSN 1662-9779

Аннотация: Solid-state reactions between Ge and Mn films are systematically examined using X-ray diffraction, photoelectron spectroscopy and magnetic measurements. The films have a nominal atomic ratio Ge:Mn = 40:60 and are investigated at temperatures from 50 to 500 °C. It is established that after annealing at ~120 °C, the ferromagnetic Mn5Ge phase is the first phase to form at the 40Ge/60Mn interface. Increasing the annealing temperature to 500 °C leads to the formation of the ferromagnetic phase with a Curie temperature TC ~ 360 K and magnetization MS ~ 140-200 emu/cc at room temperature. Analysis of X-ray diffraction patterns and the photoelectron spectra suggests that the increased Curie temperature and magnetization are related to the migration of C and O atoms into the Mn5Ge3 lattice and the formation of the Nowotny phase Mn5GeXCxOy. The initiation temperature (~120 °C) of the Mn5Ge3 phase is the same both for solid-state reactions in Ge/Mn films, as well as for phase separation in GexMn1-x diluted semiconductors. We conclude that the synthesis of the Mn5Ge3 phase is the moving force for the spinodal decomposition of the GexMn1-x diluted semiconductors. © (2014) Trans Tech Publications, Switzerland.

Аннотация: The reaction of [Cp(CO)2ReCCHPh] (1) with [Pd(PPh3)4] followed by the treatment of resulting [Cp(CO)2RePd(μ-CCHPh)(PPh3)2] (2) with diphosphines (dppe, dppp) gave new complexes [Cp(CO)2RePd(μ-CCHPh)(dppe)] (3) and [Cp(CO)2RePd(μ-CCHPh)(dppp)] (4). Treatment of the synthesized complexes with [Fe2(CO)9] led to mixtures of [Cp(CO)2ReFe(μ-CCHPh)(CO)4] (5), [(dppe)PdFe2(CO)8] (6), [CpReFe2(μ3-CCHPh)(CO)8] (7), [CpReFePd(μ3-CCHPh)(CO)5(dppe)] (8) and of 5, [(dppp)PdFe2(CO)8] (9), [CpReFePd(μ3-CCHPh)(CO)5(dppp)] (10), respectively. The main products of both reactions were trinuclear μ3-vinylidene clusters 8 and 10. Reactions of the trinuclear μ3-vinylidene ReFePd clusters 8 and 10 with Fe2(CO)9 were also studied. New complexes were characterized by IR, 1H, 13C, 31P NMR spectroscopy and cyclic voltammetry. The structure of [CpReFe2(μ3-CCHPh)(CO)8] was determined by single-crystal X-ray diffraction.
