Abstract

Thin films of Nd-Fe-B and α-Fe/Nd-Fe-B multilayer with Ti both for underlayers and overlayers were fabricated on glass substrates by means of RF sputtering. After annealing at 873-973 K for 30 min, both Nd-Fe-B films and α-Fe/Nd-Fe-B multilayer films have shown relatively large coercive fields and the minor loops of the α-Fe/Nd-Fe-B multilayer films are reversible in a certain range of demagnetization fields. These results indicate that the layers of α-Fe and Nd2Fe14B phases are exchange coupled.
