Anisotropy of optical absorption of alpha-MnS single crystal / I. S. Edelman [et al.] // Phys. Solid State. - 2001. - Vol. 43, Is. 8. - P. 1549-1551 ; Phys. Solid State. - 2001. - Vol. 43, Is. 8. - P. 1549-1551, DOI 10.1134/1.1395100. - Cited References: 11 . - ISSN 1063-7834. - Вариант Sopus

Аннотация: The optical absorption spectra of an alpha -MnS single crystal and their temperature behavior in the range from 86 to 300 K are investigated for the (100) plane in the energy range from 8 x 10(3) to 22 x 10(3) cm(-1) for the first time. Comparison of these spectra with those for the (111) plane reveals an essential absorption anisotropy in unpolarized light. The anisotropy is manifested in a much stronger splitting of the lowest energy band for the (100) plane in comparison with that for the (111) plane. With decreasing temperature, the splitting becomes smaller. Possible mechanisms for the anisotropy revealed are proposed. (C) 2001 MAIK "Nauka/ Interperiodica".

Antiferromagnet-ferromagnet transition in alpha-MnxS manganese sulfides / G. A. Petrakovskii [et al.] // Phys. Solid State. - 2001. - Vol. 43, Is. 3. - P. 493-495 ; Phys.

Аннотация: Off-stoichiometric manganese monosulfides alpha -MnxS (1 less than or equal to x less than or equal to 1.25) are synthesized, and their crystal structure and magnetic properties are studied in the 4.2- to 300-K range. The compounds have a NaCl fcc lattice. Increasing the manganese ion concentration x in the antiferromagnetic semiconductors alpha -MnxS is found to result in concentration- (x(c) similar to 1.05) and temperature-driven (T-c similar to 50 K) magnetic transitions from the antiferromagnetic to ferromagnetic state, with the cubic structure remaining unchanged.

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.

Conductivity, weak ferromagnetism, and charge instability in an alpha-MnS single crystal / S. S. Aplesnin [et al.] // Phys. Rev. B. - 2005. - Vol. 71, Is. 12. - Ст. 125204 ; Phys. Rev. B Condens.

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: 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: 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.

The ferromagnetic compound FexMn1-xS (x = 0.29) exhibits the giant magnetoresistance (GMR) effect with magnitude delta(H) = -450% in a field of 30 kOe at 50 K. Antiferromagnetic CrxMn1-xS (x = 0.5) sulfide undergoes a transition to the GMR state (delta(H) similar to -25% in a field of 30 kOe at 4.2 K) in the region of antiferromagnet-ferromagnet transition (T-c similar to 66 K). A mechanism of the GMR in these compounds is discussed. (C) 2000 MAIK "Nauka/Interperiodica".

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.

Low-temperature electronic and magnetic transitions in the antiferromagnetic semiconductor Cr0.5Mn0.5S / G. A. Petrakovskii [et al.] // Phys. Solid State. - 1999. - Vol. 41, Is. 9. - P. 1520-1524, DOI 10.1134/1.1131014. - Cited References: 13 . - ISSN 1063-7834

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.
