Temperature stability of martensite and magnetic field induced strain in Ni–Mn–Ga
Source abstract
Abstract
In single crystal Ni2MnGa that exhibits 4.6% magnetic field induced strain (MFIS) at 291 K, it is found that the effect lacks thermal stability. As the temperature rises, the MFIS decreases concomitantly with the lattice distortion. At the same time, the critical magnetic field necessary to activate twin boundary motion falls. A new intermediate martensitic phase is observed.
