摘要：

A theoretical model for investigation of an exchange bias effect in Heusler Ni50Mn25+xSb25-x alloys by Monte Carlo simulations is presented. It is shown that the exchange bias effect of Heusler Ni50Mn25+xSb25-x alloys is observed in the composition range 7.5 < x < 15 at the temperature T = 13 K. For case of Ni50Mn37.5Sb12.5 alloy, we have obtained the exchange bias field H-EB = 0.05 T at 4.6 K and a blocking temperature T-B = 46.7 K. Theoretical results are in good qualitatively agreement with experimental data.
