(Ni,Fe,Co)-based nanocrystalline soft magnets with near zero magnetostriction

Summary form only given. Nanocrystalline soft magnetic materials have been developed possessing a wide variety of compositions and concomitant properties. In an attempt to reduce losses due to stresses imposed on inductor cores, several alloys composed of (Ni,Fe,Co)-Zr-B-(Cu), have been developed to provide near zero magnetostriction. Many of these alloys; would be unsuitable for alternating current applications owing to their high intrinsic magnetocrystalline anisotropies. However, by virtue of the nanocrystalline structure with grain diameters smaller than the exchange correlation length, the effective magnetocrystalline anisotropies were considerably reduced.
