Abstract

Summary form only given. Exchange spring magnets are two phase materials composed of a hard and a soft magnetic component that can be chosen to tailor a desired magnetic property. Of special interest are exchange springs in which the hard phase is a giant magnetostrictive material due to their potential applications as transducers for microactuators. We present here a study of the magnetic properties of Fe/sub 60/Sm/sub 40//Fe/sub 95/Ta/sub 5/N/sub x/ thin films using magnetization and ferromagnetic resonance (FMR) techniques.
