High-Frequency Magnetic Properties of Nd2Fe17N3 Magnetic Powders with Nano-α-Fe Phase-Separated Surface Layers

In this study, Nd 2 Fe 17 N 3 powder was coated with transition metals and rare-earth phosphate layers. Subsequently, the phosphate layers were phase separated into outer Fe 2 O 3 and inner Nd 2 O 3 layers via heat treatment in air. Simultaneously, the phase-separated layers of nanosized α-Fe and ra...
