Magnetic-Field-Controlled Twin Boundaries Motion and Giant Magneto-Mechanical Effects in Ni-Mn-Ga Shape Memory Alloy

open access: yes, 2000
Recently, several research groups have reported on the observation of super-large more than 5% magneto-strain effect in some non-stoichiometric Ni-Mn-Ga alloys close to 5.78% value expected from the tetragonality aspect ratio of the martensite crystal ...
