摘要：

A broad band method for measuring the complex permeability of magnetic thin films, based on the measurement of the S parameters of a stripline and on the numerical resolution of the Laplace's equation according to the quasi-TEM propagation mode, is presented. The method is applied to determine the permeability spectra of CoZr amorphous thin films, in the 3 MHz to 3 GHz frequency range. The influence of the exciting magnetic field orientation in respect with the direction of the easy axis is studied. The influence of the eddy currents on the cut-off frequency observed on permeability spectra is analyzed.
