Ferromagnetic resonance in cast microwires and its application for noncontact diagnostics

Ferromagnetic resonance in glass-coated Fe-based cast amorphous microwires reveals large residual stresses appearing in the microwire core during casting. These stresses, together with magnetostriction, determine the magnetoelastic anisotropy. Ferromagnetic resonance frequency is affected, in additi...
