摘要：

In exchange-spring magnets with temperature-induced interfacial intermixing, differences in the extent of diffusion of constituent elements typically lead to local compositional changes. The authors demonstrate that adding an artificially created intermixed layer in Sm-Co/Fe exchange-spring permanent magnets enhances the exchange coupling effectiveness without modifying the local composition of the Sm-Co layer. Element- and depth-resolved magnetization measurements verify that the diffusion extent of Sm and Co is similar across the interface. (C) 2007 American Institute of Physics.
