摘要：
Thin films of Nd2Fe14B (similar to 30-60 nm) were grown with c-axis texture by means of molecular beam epitaxy. A two-phase structure is observed in both the x-ray diffraction and the hysteresis loops, due to an interfacial reaction during the initial growth. Coercivities are 1-2 T at 20 K, and the anisotropy fields are bulk-like. Microstructural analysis by atomic and magnetic force microscopies reveal lateral grain sizes of similar to 200 nm, which could explain the hard magnetic properties.
