Аннотация: The structural, electrical, and magnetic properties, as well as the magnetoresistance of polycrystalline MexMn1-xS (Me = Fe and Cr) sulfides were investigated in longitudinal magnetic fields of up to 50 kOe over the temperature range 4.2-300 K. The ferromagnetic compound FexMn1-xS (x = 0.29) exhibits the giant magnetoresistance (GMПоказать полностьюR) 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".
