Description

We developed a new thin-film permeance meter that is effective from 10 MHz to 1.5 GHz, using a microstrip pickup coil that senses the change in flux in a film sample driven in the TEM propagation mode. The microstrip pickup coil allows broader-band measurement of the permeance than a figure-8-coil, because impedance matching is provided. The influences of the exciting electric fields and the higher-order mode in the driving coil on the permeance measurement are analyzed. A strong de field (170 Oe) is applied parallel to the easy axis during the reference voltage measurement in order to eliminate the influence of the electric field.
