Ferromagnetic δ -phase manganese gallium layers with Mn / ( Mn + Ga ) = 60 % have been successfully grown on ScN(0 0 1) by molecular beam epitaxy, expanding possibilities for ferromagnetic layers on nitride semiconductors. The in-plane epitaxial relationship of manganese gallium with respect to scandium nitride is determined to be [ 1 0 0 ] MnGa / / [ 1 1 0 ] ScN and [ 1 1 0 ] MnGa / / [ 1 0 0 ] ScN . Vibrating sample magnetometry measurements indicate out-of-plane magnetization of the film, suggesting strong magnetic anisotropy along the manganese gallium c -axis.
