Abstract
An investigation of Co69Fe3.7Cr3.8Si12.5B11 amorphous alloy shows that thermally reversible isotropic short-range compositional ordering and clustering can lead to the degradation of hysteretic magnetic properties (HMPs). At temperatures below the Curie temperature (260°С), the degradation of HMPs is caused by thermally reversible directional ordering and reduces the mobility of domain boundaries. Clusterization, a thermally irreversible process observed via small-angle X-ray scatterimg, affects HMPs only during sample annealing immediately after quenching.
