Magnetic Properties and Applications of Glass-coated Ferromagnetic Microwires
Advanced Electromagnetics, 2023 A remarkable magnetic softness and giant magnetoimpedance (GMI) effect at GHz frequency range havebeen observed in glass-coated microwires subjected to appropriate postprocessing. Co-based microwires present higher GMI effect.

Giant Magnetoimpedance Effect in NiFeMo Permalloy Ribbon
Materials Transactions, JIM, 2000 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 0.3MHz.
