Influence of Annealing Time at 395-400°C on the ΔE Effect,Magnetostriction And Magnetic Anisotropy In Fe 78 Si 8 B 14 Metallic Glasses

Abstract

The Young's modulus (E), magnetostriction (ë) and magnetic anisotropy (K_s) in rapid quenching Fe₇₈Si₈B₁₄ alloy were investigated. Effects of subsequent annealing at 395-400°C are reported. Connections between ÄÅ effect and magnetic anisotropy confirm the role of structural relaxations. A relation between Å and minimum and maximum changes of magnetostriction is theoretically and experimentally pointed out.
