摘要：

Magnetization and Mossbauer measurements are reported on the hexagonal alloy system (Fe0.995Cr0.005)2P. It is ferromagnetically ordered with T(C) congruent-to 190 (+/- 10) K which is about 25 K lower than that of pure Fe2P. In the high-temperature region the Curie-Weiss law holds. The paramagnetic Curie temperature is 390 (+/- 10) K, quite in agreement with that of Fe2P. Analysis of the Mossbauer spectrum at 9 K suggests that the presence of Cr in second coordination sphere of Fe considerably lowers the internal hyperfine fields at Fe atoms although to a lesser extent than in the 1% Cr-substituted alloy.
