摘要	A proposed Nd2Fe14B-core/Nd-2(Fe, Co)(14)B-shell microstructure was realized by diffusion-processing textured Nd14Fe77B9 single-layer film with Nd100(-x)Co(x) (x= 10, 20 and 40) alloys to improve the coercivity thermal stability. The ambient coercivity was increased from around 1 T in single-layer film to nearly 2 T in diffusionprocessed films, which was due to the Nd-rich grain boundaries as seen from transmission electron microscopy (TEM) images. The coercivity thermal stability was improved by the core/shell microstructure because Nd-rich grain boundaries provided the high ambient coercivity and Co-rich shell provided the improved coercivity stability.; A proposed Nd2Fe14B-core/Nd-2(Fe, Co)(14)B-shell microstructure was realized by diffusion-processing textured Nd14Fe77B9 single-layer film with Nd100(-x)Co(x) (x= 10, 20 and 40) alloys to improve the coercivity thermal stability.
