Multifunctional behavior of Fe-doped MnNiGe magnetic equiatomic compound
چکیده انگلیسی
The exchange bias (HE=∼90 Oe for Hcool=5kOe at 5 K) and magnetocaloric effect (1.55 J/kg-K for 0-50 kOe at 5 K) of the new class of ferromagnetic shape memory alloy of nominal composition Mn0.75Fe0.25NiGe have been investigated. The sample can be thought of being derived from the parent MnNiGe alloy, where Fe was doped at the expense of Mn atom. Fe doping at Mn site brings down the martensitic transition temperature below room temperature and induces ferromagnetism in it. The presence of antiferromagnetic (AFM) clusters, due to doping disorder, in otherwise ferromagnetic (FM) compound, plays pivotal role towards the observation of multifunctionality of the studied alloy.
