Some shape memory alloys exhibit so-called temperature memory effect (TME) associated with their thermoelastic martensitic transformations. In this paper, we report that the same TME also appears in association with a first order magnetic transition between an antiferromagnetic phase and a ferromagnetic phase in FeRh. Although the TME in shape memory alloys appears only in the heating process, the TME in FeRh appears both in the cooling and heating processes. Presumably, the arrangement of antiferromagnetic domains and ferromagnetic domains is responsible for the TME in FeRh.
► Temperature Memory Effect (TME) is observed in magnetostructural transition of FeRh.
► TME in FeRh appears both in ferro–antiferro and antiferro–ferro transitions.
► The arrangement of domains is considered to be responsible for the TME in FeRh.
