Abstract
Magnetoplasticity is the large magnetic-field-induced deformation of ferromagnetic martensite. This effect is caused by a twin rearrangement. A strain-induced change of magnetization is the inverse effect. This effect is studied experimentally on a Ni-Mn-Ga single crystal. The deformation-induced change of magnetization is linear to the compressive strain and shows only small hysteresis in a loading-unloading cycle performed in an orthogonal magnetic field.
