Abstract :
Influence of transverse field annealing (HT) and cooling rate (vc) on magnetic remanence (Br), coercivity (Hc) and domain structure of the amorphous near-zero magnetostrictive Co71.5Fe2.5Mn2 Mo1Si9B14 alloy was investigated. Two step magnetic annealing was performed on 20×15×10 mm toroidal cores and on 30×10 mm pieces of ribbons. Magnetic properties dependence upon a time of preannealing was determined too. Very strong effect of HT and vc on the magnetic properties and domain structure was discussed on the base of the Kronmuller model
