摘要: Abstract We studied the correlation between magnetostriction coefficient, coercivity and Giant magnetoimpedance effect of Fe–Ni-rich microwires. As-prepared annealed Fe 47.42 Ni 26.6 Si 11 B 12.99 C 1.99 microwires present rectangular hysteresis loops. Varying time temperature annealing we observed changes (GMI). Increasing first some magnetic softening then hardening. These correlate with evolution coefficient. Decreasing coefficient after is related to formation nanocrystalline structure.
