MAGNETOIMPEDANCE EFFECTS IN NANOCRYSTALLINE Fe₈₄Zr₇B₈Cu₁ ALLOY

抄録

The annealing effect on the magnetoimpedance of nanocrystalline Fe₈₄Zr₇B₈Cu_l alloy has been investigated in conjunction with the changes of magnetic properties such as permeability, magnetic anisotropy, etc. by thermal treatment. The magnetoimpedance ratio coincides with the softness of magnetic properties of thermally treated samples. The field - annealing doesn't contribute to improve the magnetoimpedance effect in the nanocrystalline alloy.
