Abstract
The structure and magnetic properties of multilayer magnets containing a hard phase [HP≡ (Nd0.95 Dy0.05) (Fe,Co,Nb,B)5.5] and a soft phase (SP≡Fe and Fe65 Co35) have been investigated. For the nanocomposite multilayer of Si(substrate)/Ti (30 nm) [HP (x nm) SP (y nm)] nTi (30 nm), the remanence enhancement has been observed at different thickness and volume fractions of hard- and soft-phase layers. The remanence increases and the coercivity decreases with the addition of soft phase, in comparison with the results of the single-layer film. For the multilayer of Si (substrate) Ti (30 nm) [HP (15 nm) Fe (5 nm)] nTi (30 nm) annealed at 575°C for 30 min, the coercivity of the multilayer reaches a maximum at n=20. Effects of the layer thickness and volume fraction of hard- and soft-phase layers on magnetic properties and exchange coupling in the multilayer films have been observed.
