Popis:	We have explored the impact of low‐level Cu additions on the magnetic properties of melt‐spun Nd‐Fe‐B ribbons. The addition of 0.5 at. % Cu enhances the intrinsic coercivity as much as 30% over that of Cu‐free materials. Transmission electron microscopy analyses demonstrate that Cu segregates preferentially to the intergranular regions.
