摘要: Epitaxially grown Mn2VAl films were fabricated on MgO (001) single crystalline substrates by using a sputtering technique. The resulting with substrate temperatures of Ts=500 and 600 °C showed an L21-ordered structure. saturation magnetization was 150 emu/cm3 at 300 K for sample Ts=600 °C. Ferrimagnetic coupling between the Mn V magnetic moments in L21-Mn2VAl film clearly demonstrated soft x-ray circular dichroism. In previous studies, this found only polycrystalline bulk samples examined nuclear resonance.
