Description
Summary:Effect of orientation of the induced uniaxial magnetic anisotropy axis on the temperature dependences of the AE-effect for ribbons having [Fe.sub.64][Co.sub.21][B.sub.15] amorphous metal alloy composition after thermomagnetic treatment at temperatures from 270 to 330[degrees]C is investigated. The magnetic field strength at which the absolute value of the negative AE-effect is maximal decreases with increasing tilt angle of the induced uniaxial magnetic anisotropy axis with respect to the direction perpendicular to the ribbon rolling axis. This decrease is caused by the decrease in the field of the Bloch-Neel transition of charged domain walls during magnetization of the ribbon with a tilted easy magnetization axis. Keywords: amorphous metal alloys, induced magnetic anisotropy, [DELTA]E-effect, charged domain walls.
