Аннотация: The magnetic, electric, magnetoresistive, and structural properties are investigated in the sulfide solid solutions FexMn1-xS, which are based on the antiferromagnetic semiconductor alpha-MnS (the fcc NaCl lattice). Colossal negative magnetoresistance (delta(H)similar to-83% at 160 K for x similar to 0.29), comparable to that observed in La-Ca-Mn-O polycrystals and films (delta(H)similar to-90% at 100 K and 40 kOe), is observed in compounds with intermediate concentrations 0.26 x 0.4, corresponding to the region of incipient ferromagnetism.

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 correlation between the magnetic and electrical properties of the (VS)(x)(Fe2O3)(2-x) (0.9 x 1.25) oxysulfide solid solutions has been studied. The crossover of conductivity from the semimetallic to semiconducting type is accompanied by changes in the magnetic susceptibility, which are characteristic of the transition from delocalized to localized electrons.

    Electrical and magnetic properties of nanodiamond and pyrocarbon composites / N. I. Kiselev [et al.] // Russ. J. Gen. Chem. - 2013. - Vol. 83, Is. 11. - P. 2173-2181, DOI 10.1134/S1070363213110376 . - ISSN 1070-3632
Аннотация: The electrical and magnetic properties of the nanodiamond composites comprising nanodiamond, pyrolytic carbon, and nanosized pores were studied. The composites are p-type semiconductors and their resistance decreases by 12 orders of magnitude as the pyrocarbon-to-diamond ratio γ increases from 0 to 80 wt %. Evidence for paramagnetic properties of the nanodiamond composites was obtained. The observed properties are explained by increased concentration of surface Tamm states. The paramagnetic properties are explained in terms of the electron spins localized on the nanodiamond surface in the composite.

Аннотация: Electrical, resonant, and magnetic properties of intercalated copper chromium disulfide CuCrS2 are studied. It is established that CuCrS2 is an antiferromagnetic semiconductor with Neel temperature T-N = 40.7 K and an effective magnetic moment of 4.3mu(B). Anomalies in the electrical, magnetic, and resonant properties of CuCrS2 are found at T-c = 110 K, which suggest an electron transition accompanied by alteration of the valences of the 3d-metal ions.

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.

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.

Аннотация: Experimental-theoretical studies were carried out of the electrical and magnetic properties of the antiferromagnetic semiconductor Cr0.5Mn0.5S in the temperature range 4.2-300 K. A magnetic antiferromagnetic-ferrimagnetic phase transition was observed along with a semimetal- semiconductor electronic transition. Monte Carlo calculations indicate that the changes in the type of magnetic ordering and conductivity are due to the cooperative Jahn-Teller effect caused by the Cr2+ ions.

РУБ Physics, Condensed Matter

Аннотация: A study has been made of the FexV1-xS solid solutions with 0 x 0.5. For the compounds with x. 0.1, x-ray diffraction analysis discloses a V5S8 superstructure. Samples with x 0.1 are magnetically ordered at room temperature. The concentration dependences of resistivity and magnetization exhibit sharp peaks for x = 0.1 and x = 0.2, respectively. The main features of the structure and electronic properties have been qualitatively explained in terms of the three-band exciton-insulator model, and the maxima in resistivity and magnetization are assigned to the formation of localized magnetic moments with S = 1, which become delocalized with increasing x.

Аннотация: The effect of the manganese doping of vanadium monosulfide in a system of the V1-xMnxS (0 x less than or equal to 0.3) solid solutions on their structure and thermal, electrical, and magnetic properties has been investigated. The metal-dielectric transitions are revealed in the studied ranges of concentrations and temperatures. These transitions are accompanied by a change in the magnetic properties. It is demonstrated that the correlation in changes of the electrical and magnetic properties of the sulfides under investigation is characteristic of the metal-dielectric transitions in strongly correlated systems.

    Phase transitions and colossal magnetoresistance in CuVxCr1-xS2 layered disulfides / G. M. Abramova [et al.] // JETP Letters. - 2006. - Vol. 83, Is. 3. - P. 118-121, DOI 10.1134/S0021364006030088. - Cited References: 10 . - ISSN 0021-3640

Аннотация: New substances CuVxCr1-xS2 are synthesized in which colossal magnetoresistance (T-C = 95 K, delta(H) = -60%, H = 7 kOe), as well as the sequence of phase transitions with change in the conduction type and magnetic order, is observed as temperature is varied. The change found in the magnetic and electric properties of the CuVxCr1-xS2 compounds may be a consequence of a specific disintegration into Cu+Cr+S2 and CU2+Cr2+S2 and a change in the concentration relation between these electronic phases in the substance bulk.
