The authors propose a new method to measure magnetostriction of magnetic thin films using piezoelectric ceramic substrates and some feedback circuits. Conventional methods are based on the measurement of the bonding of a cantilevered substrate sample wlith a magnetic film when a magnetic field is applied in the plane of the film. The main idea of the developed method is to compensate any bending along the sample's length, changing the length of the substrate using the inverse piezoelectric effect, by the same amount of the thin films's change of length (caused by the magnetostriction).
