| Research Abstract |
Ni-Mn-X (X=In, Sn) system alloy films as metamagnetic shape memory alloys were fabricated by sputtering method. After heat treatment, the films coincidentally showed the magnetic transformation and structural phase transformation (martensitic transformation). Their martensitic transformation temperatures became higher than room temperature and lower than the Curie temperature due to control of their compositions. The alloy films are expected as magnetic-field induced actuator materials, which enable the quick response and remote control.
