Influence of heat-treatment on magnetic, magnetostrictive and piezomagnetic properties and structure of Fe_(64)Ni_(10)Nb_3Cu_1Si_(13)B_9 metallic glass

摘要

The magnetic and piezomagnetic properties of the strip-shaped samples of the Fe_(64)Ni_(10)Nb_3Cu_1 Si_(10)B_9 alloy were investigated after annealing in vacuum in the temperature range 100-600℃. The coercivity was in the range from 5 to 50 A/m, the saturation induction about 1.25 T and magnetostriction (22-26) x 10~(-6) (after annealing up to 480℃). The magnetomechanical coupling coefficient reached the value of 0.62, and the elasticity moduli were changing from 70 to 205 GPa.
