Abstract
A giant magnetoresistance, reaching 74% in a magnetic field of 38 T at 3 K, was observed in the CuCr1.6Sb0.4S4 semiconductor spinel. The magnetic prop erties point to the existence of a magnetic two-phase state in this compoun d. The giant magnetoresistance was explained by the existence of the magnet ic two-phase state due to strong s-d exchange. (C) 2000 MAIK "Nauka/Interpe riodica".
