Effect of torsional stresses on the magnetoimpedance of amorphous wires with negative magnetostriction
A model to describe the effect of torsional stresses on the magnetoimpedance of amorphous wires with negative magnetostriction is suggested. An approximate expression for the impedance with regard to
Stress-induced magnetic hysteresis in amorphous microwires probed by microwave giant magnetoimpedance measurements

The tensile stress dependence of magneto-impedance (MI) in CoSiB and CoFeSiB amorphous wires is reported. A phenomenological model for the transverse susceptibility based on a simple domain
A theoretical model for the giant magnetoimpedance in ribbons of amorphous soft‐ferromagnetic alloys
Giant magnetoimpedance (GMI) measured in ribbons of the soft ferromagnet Co75−xFexSi15B10 annealed in the presence of a transverse magnetic field exhibits peaks in its field dependence. The GMI is

The effect of the torsion strain on the electrical impedance in (Co0.95Fe0.05)72.5Si12.5B15 amorphous wire has been investigated. The torsion stress impedance ratio, defined as
Coupled core-shell model of magnetoimpedance in wires
Magnetoimpedance (MI) has been studied extensively in soft magnetic wires and plates. Although a general theoretical basis has evolved, several details remain poorly understood. In particular, the
