| Abstract | The structure and magnetic properties of multilayer magnets containing a hard phase [HP equivalent to(Nd0.95Dy0.05)(Fe,Co,Nb,B)(5.5)] and a soft phase (SP equivalent to Fe and Fe65Co35) have been investigated. For the nanocomposite multilayer of Si(substrate)/Ti(30 nm)/[HP(x nm)/SP(y nm)]n/Ti(30nm), 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)]n/Ti(30 nm) annealed at 575 degrees 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.
