Tuning exchange bias effect in Ni50Mn36Sn14 Heusler alloy

摘要：

　　The tuning exchange bias HE at martensitic state of Ni50Mn36Sn14 alloy has been investigated by means of hysteresis loop measurement.It was found that the whole loop can be tuned by HFC from a double-shifted to a single-shifted hysteresis loop, leading to an appearance of maximum HE at HFC =0.5 kOe.This behavior could be ascribed to the competition between two types of AFM clusters and HFC, which exhibits predominantly at low H-FC range, while the competition between FM clusters and HFC, which becomes predominant at high HFC range.
