Effect of Annealing under Load on the Magneto-Optical Properties of Iron-Based Nanocrystalline Ribbons
摘要
Abstract
The effect of annealing under load on the magneto-optical properties of magnetically soft nanocrystalline Fe68.5Cr5Si13.5B9Nb3Cu1 ribbons obtained by rapid quenching from the melt and then annealed at a temperature of 520°C for 2 h with no load and under a specific load of 150 MPa is studied. The surface magnetic hysteresis loops with a simultaneous visualization of changes in magnetic domain structure have been studied using a magneto-optical Kerr magnetometer. The obtained experimental data indicate the fact that annealing under load leads to the formation of induced magnetic anisotropy and affects the samples in the magnetic field.
