Resumen
In this work the behavior of the magnetoimpedance (MI) in ferromagnetic
multilayered (Ni81Fe19/Cu) produced by magnetron sputtering was studied. In all
measurements, the probe current was applied perpendicularly to the film surface. The MI
measurements were performed in the frequency range 100kHz - 1.8GHz with an HP-4396B
impedance analyzer and a specially designed sample holder. Magnetoimpedance ratios of
150% were obtained in some of the studied samples.
