Abstract: A fully automated system, designed to measure both components of the impedance as functions of applied field (up to 130 Oe), current intensity (up to 20 mA) and frequency (up to 1 MHz), is presented. Also, this apparatus allows impedance relaxation to be recorded. High sensitivity is achieved by using lock-in technique, and weak relative changes of the impedance, down to an order of 0.1%, can be observed.
