Properties of amorphous FeZrBiSiB alloy on relaxation

摘要

The relaxation phenomena of the amorphous FeZrBiSiB alloy have been investigated by DSC and electrical and magnetic measurements. It is found that there exist two different relaxation stages of the structural relaxation processes. The mechanism of forming these two relaxation stages is analyzed by the idea of short‐range localized atomic arranging movement and medium or long‐range cooperative atomic arranging movement. We consider that the effect of the annealing treatments on the Curie temperature of the specimens is caused by the additive effect of ferromagnetic and antiferromagnetic exchange interaction.
