| Popis: | Magnetic and transport properties of iron nitride compounds are closely related to the ratio of Fe:N. In this letter, we report a successful growth of pure single-phase N-rich iron nitride (e-Fe2–3N and γ″-FeN) films on Al2O3. e-Fe2–3N shows a ferromagnetic behavior while γ″-FeN shows a nonmagnetic behavior. Same with other N-poor iron nitrides, e-Fe2–3N presents metallic transport nature. In particular, weak localization in quantum interference effects (QIEs) and spin-dependent scattering phenomena are observed in e-Fe2–3N. Different with other known iron nitrides, γ″-FeN shows semiconductor-like transport property. These findings offer great opportunities for designing magnetoelectronic devices based on iron nitride compounds. |
