摘要：
The frequency dependence of the magnetoimpedance of an amorphous magnetic wire displays a behavior that appears to be ferromagnetic resonance, at a frequency of about 900 kHz. A helical anisotropy is induced in this wire by applying a torsional strain. The second harmonic component of the magnetoimpedance signal is also investigated. The reinforcement of this component by the helical magnetoelastic anisotropy is analyzed in terms of the asymmetry in coercivity of the circumferential hysteresis loops of the wire.
