  Giant magneto impedance (GMI) effect for as-cast
Vitrovac$^{\textrm{\scriptsize\textregistered}}$ amorphous ribbons
(Vacuumschmelze, Germany) in two configurations (parallel and normal to the
ribbon axis) is studied over the frequency range [0.3-400 MHz] and under static
magnetic fields -160 Oe $< H_{dc} < $+160 Oe. A variety of peak features and
GMI ratio values, falling within a small field range, are observed and
discussed.
