Abstract

We report a structural and magnetization study of the Heusler compound Fe2MnGa. The sample shows a single cubic phase with a large Curie temperature (TC) of 750 K. The sample undergoes a disorder induced first-order ferromagnetic (FM) to antiferromagnetic (AFM) transition around the room temperature. This transition results in a mixed AFM and FM phases. A large exchange bias (EB) of 0.12 T is observed for a cooling field of 0.5 T. The EB decreases to a near saturation value of 0.07 T for a cooling field of 7 T. The ac-susceptibility measurements confirm that no spin-glass type of magnetic state is present in the sample. © 2013 American Institute of Physics.
