Abstract

We report the magnetic-field-induced transition in a Co_51.7Cr_26.8Ga_10.6Si_10.9 alloy. Because of the unique reentrant martensitic transformation behavior, the reentrant parent phase was found to be induced by pulsed high magnetic fields up to 550 kOe, which is a new type of magnetic-field-induced transition of martensite. The critical magnetic field-temperature H–T phase diagram was completed, from which the entropy change for the reentrant martensitic transformation was estimated using the Clausius-Clapeyron relationship. A good consistency was found for the entropy change in comparison with those from earlier reports.
