摘要	The structural and magnetic properties of rare-earth nanocomposite magnets of a (NdDy)(Fe,Co,Nb,B)(5.5) single layer and a (Nd,Dy)(Fe,Co,Nb,B)(5.5)/alpha-Fe multilayer prepared by sputtering and heat treatment have been investigated. Incomplete exchange coupling behaviour is observed in the Ti-buffered NdDyFeCoNbB + 40 wt%Fe single layer magnet. After annealing, the laminated nanostructure consisting of mutually dispersed soft and hard phases results in remanence enhancement. The optimum magnetic properties of J(r) = 1.11 T, mu(0i) H-c = 0.88 T and (BH)(max) = 192 kJ m(-3) are achieved in the multilayer magnet annealed at 550degreesC for 30 min. The designed multilayer film with thinner soft magnetic layers may favour the formation of more ideal nanostructures for exchange coupling between soft- and hard-magnetic phases.; The structural and magnetic properties of rare-earth nanocomposite magnets of a (NdDy)(Fe,Co,Nb,B)(5.5) single layer and a (Nd,Dy)(Fe,Co,Nb,B)(5.5)/alpha-Fe multilayer prepared by sputtering and heat treatment have been investigated.
