Abstract

The results of the influence of load annealing on the magneto-optical properties of soft magnetic nanocrystalline e68.5Cr5Si13.5B9Nb3Cu1 ribbons obtained by rapid quenching from the melt and then annealed at a temperature of 520°C for 2 h without load and using a specific load of 150 MPa are presented. The near-surface magnetic hysteresis loops and simultaneous visualization of the changes of magnetic domain structure were measured using a magneto-optical Kerr magnetometer. The obtained experimental data that annealing underload leads to the formation of induced magnetic anisotropy and affects the magnetic field behavior of the samples.
