Abstract :
Results on the correlation between ferromagnetic resonance and magneto-impedance responses in soft magnetic Fe-based microwires with nanocrystalline structure are reported for the first time. The evolution of the magneto-impedance effect with structural changes starting from the as-cast amorphous state up to nanocrystallization and further crystallization is interpreted through changes induced in the surface magnetic anisotropy and magnetization process of such wires, that are studied by means of ferromagnetic resonance
