Abstract

γ'-Fe₄N film was epitaxially grown on a SrTiO ₃(001) substrate by molecular beam epitaxy using solid source Fe and nitrogen radical beam by electron cyclotron resonance plasma. Under the similar growth condition, we tried to grow γ'-Fe₄N films epitaxially on a Si(100) substrate, because the lattice mismatch is smaller on Si(100) (1.3%) than that on SrTiO₃(001) (3%). It was found from x-ray diffraction measurements that ε-Fe₃N films were formed instead of γ'-Fe₄N, differently from our prediction.
