Abstract:
agnetic shape memory alloys are a new kind of metallic functional materials developed in 1990s. The magnetic shape memory alloys possess both thermoelastic martensitic transformation and magnetic transition. Therefore the shape memory effect can be controlled by the magnetic field. Besides, these alloys also exhibit magnetoresistance, magnetocaloric effects, etc.
