Ferromagnetic shape memory effects in Ni 2MnGa thin films were investigated. Structural characterization of the films indicate that films grow pseudomorphically on GaAs (001) substrates. The films exhibit coercivity of ∼50 Oe and saturation magnetization of ∼250 emu/cm 3. Observation using a polarized-light optical microscope showed large movement of the cantilevers.
