Аннотация: Magnetization of the cation-substituted CoxMn1-xS sulfides upon cooling in zero and 100 Oe magnetic fields at the temperatures 4-300 K has been measured. Permittivity of these materials at frequencies from 1 to 100 kHz in magnetic and dc electric fields in the 100-300 K temperature range has been determined. Change in the dielectric permittivity under an external magnetic field is found to have a maximum in the temperature ranges of T-1 similar to (110-120 K) and T-2 similar to (230-250 K). Formation of spontaneous magnetic moment and the rise of magnetic susceptibility are revealed at the same temperatures in the CoxMn1-xS solid solutions. Features of the magnetoelectric properties of the sulfides have been explained by orbital ordering.

Аннотация: Regions of the existence of sulfide Gd (x) Mn1 - x S and selenide Ti (x) Mn1 - x Se solid solutions have been identified. Their electrical and thermoelectric properties have been studied in the temperature range 80-900 K. It has been established that the substitution of Gd2+ and Ti2+ ions for Mn2+ cations initiates reversal of the type of charge carrier with respect to the starting compounds MnS and MnSe. The cation substitution in solid solutions brings about a change from the hole conduction (alpha 0) characteristic of the manganese monosulfide and monoselenide to the electronic conduction (alpha 0).

Аннотация: The magnetization of cation-substituted CoxMn(1-x)S sulfides upon cooling in zero magnetic field and in a field in the temperature range 4-300 K has been measured and the resistance versus magnetic field (up to 10 kOe) dependences have been obtained. Magnetoresistance and temperature hysteresis of magnetization versus prehistory are found at the magnetic field H < 0.1 T and at T < 240 K. The interrelation between the magnetic and elastic subsystems of the CoxMn1-xS solid solutions has been established. A jump in the coefficient of thermal expansion is observed at the Neel temperature. The features of the physical properties are explained by orbital ordering. (C) 2010 Elsevier Ltd.

Аннотация: The structural, magnetic, electrical, and thermoelectric properties of GdXMn1-XS (0.01 <= X <= 0.3) solid solutions synthesized for the first time on the basis of alpha-MnS have been studied experimentally in the temperature range 77-1000 K in magnetic fields up to 10 kOe. The synthesized samples are antiferromagnetic semiconductors with an NaCl-type cubic lattice typical of a-MnS. Both concentration (X-c = 0.3) and temperature (T-c = 450 K) metal-insulator phase transitions have been observed. The concentration metal-insulator transition is accompanied by a decrease in resistivity and thermopower by twelve and two orders of magnitude, respectively, with the change in conductivity from p-type to n-type.

Аннотация: We have studied the resistivity and thermoelectromotive force (thermo emf) in a temperature range of T = 80-1000 K, the magnetic susceptibility and magnetization in a temperature range of T= 4.2-300 K at an external magnetic field of up to 70 kOe, and the structural characteristics of CoxMn1 - S-x sulfides (0 <= x <= 0.4). Anomalies in the transport properties of these compounds have been found in the temperature intervals Delta T-1 = 200-270 K and Delta T-2 = 530-670 K and at T-3 similar to T-N. The temperature dependences of the magnetic susceptibility, magnetization, and resistivity, as well as the current-voltage characteristics, exhibit hysteresis. In the domain of magnetic ordering at temperatures below the Neel temperature (TN), the anti ferromagnetic CoxMn1 - xS sulfides possess a spontaneous magnetic moment that is explained using a model of the orbital ordering of electrons in the t(2g) bands. The influence of the cobalt-ion-induced charge ordering on the transport and magnetic properties of sulfides has been studied. The calculated values of the temperatures corresponding to the maxima of charge susceptibility, which are related to a competition between the on-site Coulomb interaction of holes in various subbands and their weak hybridization, agree well with the experimental data.

Effect of the orbital ordering on the transport and magnetic properties of MnSe and MnTe / S. S. Aplesnin [et al.] // Phys. Solid State. - 2007. - Vol. 49, Is. 11. - P. 2080-2085, DOI 10.1134/S106378340711011X. - Cited References: 19 . - ISSN 1063-7834

Аннотация: This paper reports on the results of measurements of the conductivity in MnSe and MnTe polycrystalline samples under thermal cycling in the temperature range 80 T 300 K in magnetic fields of up to 5 kOe. Manganese selenide MnSe is found to exhibit a magnetoresistive behavior below the Neel temperature. The specific features revealed in the temperature dependences of the magnetic susceptibility and the electrical resistivity in some temperature ranges are accounted for in terms of magnetic ordering, which is mediated by the interaction of the pseudoorbital moments with spins.

Аннотация: The temperature dependence of resistivity, magnetization, and electron-spin resonance of the α-MnS single crystal were measured in temperature range of 5 K < T< 550 K. Magnetization hysteresis in an applied magnetic field up to 0.7 T at T=5, 77, and 300 K, irreversible temperature behavior of magnetization, and resistivity were found. The obtained data were explained in terms of a degenerate tight binding model using random phase. approximation. The contribution of holes in t(2g) and e(g) bands of manganese ions to the conductivity, optical absorbtion spectra, and charge instability in α-MnS were studied. Charge susceptibility maxima resulted from the competition of the on-site Coulomb interaction between the holes in different orbitals and small hybridization of subbands were calculated at T = 160, 250, and 475 K.

Аннотация: The electrical properties and the Hall effect in the FexMn1-xS magnetic semiconductors (0less than or equal toxless than or equal to0.5) have been experimentally studied in the range 77-300 K in magnetic fields of up to 15 kOe. The cation-substituted sulfides with 0.25less than or equal toxless than or equal to0.3 possessing colossal magnetoresistance (CMR) were established to be narrow-gap semiconductors with carrier concentrations nsimilar to10(11)-10(15) cm(-3) and high carrier mobilities musimilar to 10(2)-10(4) cm(2) V-1 s(-1). It is believed that the CMR effect in these sulfides can be explained in terms of the model of magnetic and electron phase separation, which is analogous to the percolation theory in the case of heavily doped semiconductors.

MAGNETORESISTANCE
Аннотация: The electrical resistivity of single crystal alpha-MnS in crystallographic directions [111] and [100] was found to be anisotropic in the temperature interval 77-300 K. The change in activation energy below the Neel temperature was determined. Magnetoresistance was revealed, and reversal of its sign in the (111) plane above the Neel point was found. The experimental data are analyzed in terms of the s-d model, with the manganese ion holes interacting with localized spins assumed to be free carriers. (C) 2004 MAIK "Nauka/Interperiodica".

Аннотация: The resistivity and the optical absorbtion spectra of single crystal alpha-MnS are studied in the temperature range 80-300 K along two directions [100] and [111]. Strong anisotropy of the resistivity, and the shift of absorbtion spectra band edge below T < 160 K are explained in terms of model involving delocalized holes in 3d-band manganese ions interacting with localized spins by using the sd-model.
