We have examined the condition for the rearrangement of martensite variants (RMV) by magnetic field in a wide temperature range for three types of Ni-Mn-Ga ferromagnetic shape memory alloys: a Ni 2 MnGa with the 10M martensite, a Ni 2.02 Mn 1.09 Ga 0.89 (at.%) with the 14M martensite and a Ni 2.14 M
## Abstract Martensitic transformations and characteristics of the magnetic‐field‐induced strain (MFIS) on a nearly stoichiometric Ni~51~Mn~25.5~Ga~23.5~ single crystal have systematically been investigated by various methods, such as ac magnetic susceptibility, resistance, strain measurements and
