H. Chiriac et al., COMPARATIVE-STUDY OF THE GIANT MAGNETO-IMPEDANCE EFFECT IN COFESIB MAGNETIC AMORPHOUS RIBBONS AND WIRES, Materials science & engineering. A, Structural materials: properties, microstructure and processing, 226, 1997, pp. 646-649
We present a comparative study of the magneto-impedance effect in Co68
.15Fe4.35Si12.5B15 amorphous ferromagnetic wires and ribbons. The magn
eto-impedance measurements indicate that the magneto-impedance effect
is generally more sensitive in the wire-shaped samples in comparison w
ith the ribbon-shaped ones. The obtained results are interpreted on th
e basis of the circumferential magnetic permeability of the wire and t
he transverse permeability of the ribbon, correlated with the specific
magnetic domain structures. (C) 1997 Elsevier Science S.A.
