Co-based ferromagnetic Heusler compounds show high spin polarization combined with high Curie temperature of ≈700 K. In this study, we demonstrate the epitaxy of Co2MnGa Heusler alloy on flexible muscovite substrate, which paves a way toward flexible spintronic devices. The epitaxial Co2MnGa Heusler film on muscovite substrate was prepared by magnetron sputtering. Muscovite is chosen as a flexible substrate for Heusler alloy since its melting point meets growth condition for epitaxy. The epitaxy was characterized by X-ray diffraction and the epitaxial relationship between the substrate and the film was found to be [110] Mica||[1 -1 0]Co2MnGa. The bending affects the magnetization and the transport properties of the thin films. The saturation magnetization is increased by 7.6 percent under bending condition. The demonstration of Co2MnGa/muscovite heteroepitaxy provides a new perspective on developing devices with a huge potential for flexible spintronic.
