With the intention to reduce Dy content in NdFeB based magnets, 50 at.% Y substituting Dy was previously successfully employed to improve the remanence and thermal stability of the nanocomposite [Nd0.8Dy0.2]10Fe84B6 alloy without the energy product reduction. In this work, introducing Zr into Y subs...
