Paper Abstract

We studied magnetic and electric properties new magenetic semicondcutors CuCr1.5Sb0.5S4 with Co. All compounds are characteristic for antiferromagnetics. A giant negative magnetoresistance has been found in the new magnetic semiconductors xCoCr2S4 - (1-x)CuCr1.5Sb0.5>S4, (x=0.25;0.5). Magnetoresistance is practically absent in CuCr1.5Sb0.5S4 and does not exceed 2% in CoCr2S4. The giant magnetoresistance and the postivie value of e are evidence for the existence of afmons in compounds with Ni.
