Magnetoimpedance spectra of soft magnetic wires are characterized by peaks
of the real part of the impedance at frequencies f(0) which increase with t
he strength of the applied field, H-0. In the high-field region, f(0)(2) va
ries linearly with H-0 with a slope that depends on the saturation magnetiz
ation and the gyromagnetic ratio; in the low-held region, the plot f(0)(2)-
H-0 shows a near-zero intercept at H-0 = H-K. Given the gyromagnetic ratio,
both the saturation magnetization and the anisotropy held can be determine
d from the variation of f(0)(2) vs. H-0. (C) 1999 Elsevier Science B.V. All
