Giant Magnetoimpedance Effect in NiFeMo Permalloy Ribbon

抄録

In the present paper, the dc longitudinal field and ac frequency dependence of the magnetoimpedance, magnetoresistance, magnetoreactance and magnetoimpedance-phase of NiFeMo permalloy ribbon are investigated. The value of the magnetoimpedance ratio (Z(0)−Z(5172A·m⁻¹))⁄Z(0) of NiFeMo permalloy ribbon can reach 39.54% at 0.3 MHz. We also found that the change ratios of the magnetoimpedance (Z(0)−Z(5172A·m⁻¹))⁄Z(0), the magnetoresistance ratio (R(0)−R(5172A·m⁻¹))⁄R(0) and the magnetoreactance ratio (X(0)−X(5172A·m⁻¹))⁄X(0) intersect at 0.27 MHz where the change ratio of the magnetoimpedance phase (θ(0)−θ(5172A·m⁻¹))⁄θ(0) is zero.
