Abstract

In this paper, we present results on the preparation and magnetic characterization over a wide frequency range of (Fe,Co,Ni)/sub 90-x/M/sub 10/B/sub x/ (x = 5-30 at%) (M= Zr, Ti) bulk amorphous alloys. The materials were prepared by Cu mould casting method. Ac magnetic permeability (/spl mu//sub e/), electrical resistivity (/spl rho//sub RT/), as well as the temperature dependence of saturation induction (B/sub s/) and coercive field (H/sub c/) were determined by using an AC fluxmetric method in fields no larger than 1000A/m.
