Abstract

Textured thin films of nominal composition Ni0.50(MnGa) 0.50 were sputter deposited on Si substrates and studied by x-ray diffraction, micromechanical displacement, dc magnetization, and ferromagnetic resonance (FMR). We report the observation of spin wave resonances in this alloy, yielding a spin wave stiffness of D=200meVÅ2 at 300 K. A marked thermal hysteresis is observed in the temperature-dependent FMR data arising from the reversible martensitic transition.
