摘要: The values of the magnetostriction constant, λs, Co-based glass-coated microwires have been investigated by using small-angle magnetization rotation (SAMR) method. Performing systematic measurements, we were able to choose appropriate measurement conditions achieving a high-precision result. From dependence evaluated coefficient on annealing conditions, influence internal stresses value and heat treatment nearly zero magnetostrictive microwires. We observed changes sign after annealing. maximum time is explained considering superposition stress relaxation ordering beginning crystallization process.
