Abstract

Changes in engineering magnetostriction, λ_c, with annealing of undrawn furnace-annealed iron-based amorphous wires are presented. The peak λ_c falls initially due to progressive stress relief. With further annealing surface crystallization is initiated and increases, leading to an increase in the peak λ_c. The peak λ_c approaches the theoretical maximum, corresponding to an easy axis of magnetization oriented perpendicular to the wire axis, after annealing for sixty minutes at 470°C
