The last compound of the system under investigation CuCr2S4 is a well studied metallic ferromagnetic (FM) with TC = 364 to 420 K with a spinel structure. The detailed description of this compound is given in / 6 / .The system of solid solution CuxMnl-xCr2S4 was studied in / 7 / . According to the data given in / 7 / for a compound with x = 0.2, p = 1300 Rcm (T = 300 K ) , however, the Curie temperature of the compounds with x = 0.1 and 0.2 has not been measured. It is pointed out in 171 that the phase transition temperature of the Yafet-Kittel structure -FIM decreases upon introducing CuCr2S4 intoMnCr2S4 with x = 0.05 to 3.5 K and with x = 0 . 2 is not detected up to 1 . 6 K .'1 Leninskie gory, SU-117234 MOSCOW, USSR.
