Title: Ferromagnetic resonance in soft-magnetic metallic glass nanowire and microwire

We report the magneto-impedance measurements in soft-magnetic Co{sub 36}Fe{sub 36}B{sub 19}Si{sub 5}Nb{sub 4} metallic glass nano/micro wires produced by gas atomization. The wire impedance varies with external magnetic fields and the impedance peak position depends on the frequency, indicating ferromagnetic resonance. The postulation of anisotropy directions in ferromagnetic resonance allows to the determination of magnetic anisotropies in the wire. By decreasing the wire diameter, the reduction of magnetic anisotropy is observed.
