Analysis of phase
composition of Co-P alloy powders using magnetometric data / L. A. Chekanova [et al.]> // Phys. Metals & Metallogr. - 2013. -
Vol. 114
. Is. 2. - P. 122-128
DOI
10.1134/S0031918X1302004X
Аннотация:
A new method for the quantitative estimate of the phase composition of a multiphase ferromagnetic alloy is suggested that is based on measuring the temperature and field dependences of the magnetization. The phase composition of ultrafine Co-P powders is characterized. Phase diagrams of nonequilibrium Co-P solid solutions are constructed on particle size, i.e., the phosphorus concentration coordinates.

Аннотация:
We have synthesized magnetic powders of the magnetite-maghemite series by the chemical reaction of the FeSO4 iron salt and the natural arabinogalactan polysaccharide. These particles with a high magnetization value (∼ 300 Gs) represent a mixture of spherical particles and nanorods. Particles of a spherical shape (diameter of ∼ 5–6 nm) show a superparamagnetic behavior at room temperature, while rods with a diameter of ∼ 5 nm and a length of 30 nm are magnetic. We have prepared sol samples based on the nanoparticle aqueous solution of arabinogalactan. Our results on the magnetism of the circular dichroism (MCD) on sol are consistent with the of Mössbauer spectroscopy data.

Аннотация:
The comparison between the magnetic properties of materials with different curvature and spatial distribution of nanograins, such as particles (3D spatial distribution) and multilayer films (2D) was carried out. Functionally graded Co(P)/Ni(P) and Co(P)/CoNi(P) specimens have been fabricated by electroless deposition. The magnetic and structural properties are characterized by electron microscopy, X-ray diffraction, ferromagnetic resonance spectroscopy, and vibrating sample magnetometer. It was demonstrated that the interaction between the Ni(P) core and Co(P) shell of particles could form the functionally graded materials with tailored structure and coercive force. Furthermore, it was found that the magnetic parameters (the local anisotropy field, ferromagnetic resonance linewidth, and coercivity) are mainly determined by the artificially created interface boundaries for all grains’ spatial distribution. The magnetic anisotropy field and coercivity of Co(P)/Ni(P) flat films were characterized by lower values than those for spherical shell of particles with the same composition, produced by the same method.

Аннотация:
A porous polymer loaded with segmented nanorods of magnetic metal is very promising for the design of novel microwave devices. Arrays of bi-segmented Ni/Co and core-shell Ni@Co rods were prepared by electroless deposition into porous of polycarbonate track etched membrane. An intrinsic effective magnetic field of the magnetic composite nanorods aligned in the nonmagnetic template was studied by magnetization curves and ferromagnetic resonance. The effect of the interface boundaries for two types of bi-segmented rods with coaxial and along-axis Co/Ni segmentation to effective field was established.

Аннотация:
Characteristics of random magnetic anisotropy in ferromagnetic films of amorphous Co90P10 and nanocrystalline Ni75C25 , Fe80B4C16 , and Co80C20 alloys and also in multilayer films [Co93P7(x)/Pd(14 Angstrom)](20) and [Co90P10(x)/Pd(14 Angstrom)](20) obtained by various technological procedures were studied experimentally. It was found that the spatial dimensionality (d) of the system of ferromagnetically coupled grains (2R(c)) in the materials under study determined the exponent in the power dependence of the approach of magnetization to saturation in the region of fields H 2A / MRc2. The dependence DeltaM similar to H-1/2 was observed for nanocrystalline and amorphous films with a three-dimensional grain arrangement. The approach to saturation in multilayer films with a two-dimensional grain arrangement in an individual magnetic layer follows the law DeltaM similar to H-1. The main micromagnetic characteristics of random anisotropy, such as the ferromagnetic correlation radius R-f and the average anisotropy [K] of a ferromagnetic domain with a size of 2R(f) , were determined for multilayer Co/Pd films. Correlation was found between the coercive field and these characteristics of random anisotropy. (C) 2000 MAIK "Nauka / Interperiodica".

Аннотация:
Magnetic microspheres with nonmagnetic acrylic glass core were fabricated using electroless deposition. There are favorable conditions for magnetic flux closure within each particle. As a result, the dipole-dipole interaction in the powder of such microspheres is reduced drastically. This is the key difference between powders of magnetic microspheres and powders of full magnetic spherical particles witch behavior is significantly affected by the dipole-dipole interaction. The magnetic hysteresis in the cobalt microspheres with nonmagnetic core is significantly large then in the full cobalt particles produced using the same technique.

Аннотация:
Confident effect of five magnetic composite nanoparticles (FeP@Ag, FeP@Pd, CoP, NiP, Fe2O3@AГ) on growth of test bacteria colonies (Acinetobacter baumannii, Еscherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus) in five replicates each is considered. Reliable inhibitors of colonies of all five test bacteria were nanoparticles FeP@Ag. CoP nanoparticles are reliable inhibitors of growth of 4 test bacteria (except for test bacteria Escherichia сoli). NiP nanoparticles are reliable inhibitors of growth of 2 test bacteria: Escherichia сoli and Klebsiella pneumoniae. Bacteria Escherichia сoli were most sensitive to the effect of magnetic nanoparticles; and bacteria Pseudomonas aeruginosa and Staphylococcus aureus were most resistant to the effect of magnetic nanoparticles. The prospects of the method are in the possibility of multiple reuse of the magnetic particles with antimicrobial properties for bacterial decontamination of the studied sources of water and removal of magnetic nanoparticles from the treated liquids by electromagnet. The method can find use in water treatment facilities for household, Industrial and medical wastes.

Аннотация:
The deposition kinetics, structure and magnetic properties of electroless deposited films Ni-P were investigated depending on the amount of sodium hypophosphite in the electroless bath. It was found that the film deposition rate is linear and unambiguously varies with the hypophosphite content from 2 to 13 g/l and from 23 to 25 g/l. The deposition rate varies widely in the hypophosphite concentration range from 13 to 23 g/l. The films are composed of amorphous Ni-P phase and fcc Ni-P solid solution with phosphorus content from 1 to 4 at.% P according to X-ray diffraction. The partial amount of amorphous phase is increased with concentration of sodium hypophosphite. The ferromagnetic resonance field is independent on the concentration of sodium hypophosphite, which assumes to be result from the laminated allocation of the amorphous and fcc phases in the film. © (2014) Trans Tech Publications, Switzerland.

Аннотация:
The properties of Co-SiO2 nanogranular composite films, containing a Co volume fraction ranging from 0.3 to 0.8, have been characterized by means of magnetic measurements, NMR study, and ferromagnetic resonance. Thermal decrease of CoX(SiO2)100-X magnetization follows the T3/2 law and allows to estimate the exchange interaction constant A. With growing nominal Co content the transitions from granular to continuous structural state at 36% Co are registered by FMR measurements. The spectrum of standing spin-wave has been detected in the perpendicular experiment configuration for films with the Co content above 52 vol. %. It is found that the type of the dispersion relation of spin waves in Co-SiO2 composite films is affected by the exchange coupling fluctuations.

Аннотация:
The magnetization correlation function for two-phase one-dimentional chain of the ferromagnetic exchange-coupled nanoparticles with a random anisotropy was calculated. The dependence of the magnetic correlation radius and the average magnetic anisotropy constant on the intrinsic size of the phase inhomogeneity was founded. The data allows estimating the applicability limits of the analytical equations for the magnetization curves approaching saturation of two-phase ferromagnetic nanomaterials.

Аннотация:
The energy gap appearing in the spin-wave spectrum as a result of Bragg scattering by the modulation period q = 2 pi/(d(1)+d(2)) Of a one-dimensional superlattice is observed by the method of spin-wave resonance in Co/Pd multilayer films. It is shown that this gap is asymmetric: The ''positive'' deviation is from two to three times greater than the ''negative'' deviation. (C) 1996 American Institute of Physics.

Аннотация:
The resonance microwave absorption in amorphous FeSiBNbCu ribbons with different compositions obtained by rapid quenching from the melt has been investigated. It is shown that the effective magnetization calculated from the resonance field linearly decreases with increasing boron and copper impurity concentrations and the total number of nonmagnetic impurity atoms in the iron-based FeSiBNbCu ribbons.

Аннотация:
It has been found that the magnitude and sign of exchange interaction between Co(5 nm) and CoNi(5 nm) ferromagnetic layers through Pd depend on magnetization orientation of ferromagnetic layers. If magnetization is oriented in a layer plane, exchange interaction can be both ferromagnetic and antiferromagnetic. If magnetization orientation is orthogonal to a layer plane, the exchange constant is always positive at d(Pd)d(c) and equals zero at d(Pd)d(c) (d(c) is the characteristic length).
