Effect of transverse field annealing and rate of cooling on magnetic properties of the amorphous Co/sub 71.5/Fe/sub 2.5/Mn/sub 2/Mo/sub 1/Si/sub 9/B/sub 14/ alloy

摘要

Influence of transverse field annealing (H/sub T/) and cooling rate (v/sub c/) on magnetic remanence (B/sub r/), coercivity (H/sub c/) and domain structure of the amorphous near-zero magnetostrictive Co/sub 71.5/Fe/sub 2.5/Mn/sub 2/Mo/sub 1/Si/sub 9/B/sub 14/ alloy was investigated. Two step magnetic annealing was performed on 20/spl times/15/spl times/10 mm toroidal cores and on 30/spl times/10 mm pieces of ribbons. Magnetic properties dependence upon a time of preannealing was determined too. Very strong effect of H/sub T/ and v/sub c/ on the magnetic properties and domain structure was discussed on the base of the Kronmuller model.
