Description

The temperature-dependence of strain under constant magnetic-fields is studied in Ni-Mn-X (X:Ga,In,Sn,Sb) and Ni-Mn-In-X (X:Ga,Sn,Sb) polycrystalline ferromagnetic Heusler alloys which undergo a martensitic transformation close to room-temperature. The applied magnetic-field influences the nucleation of martensite so that decreasing the temperature under a magnetic field leads to large length changes between the austenite and martensite states. The length-change within the martensitic state varies with the magnitude of the cooling-field. This is related to the variant-orientation during martensite nucleation. These strain-data provide information on the easy axis of magnetization
