ABSTRACT:
An object of the present invention is to reduce a leakage current of a Pb Zr Ti O base ferroelectric thin film when a voltage is applied. A ferroelectric thin film comprising a composition of PbZr.sub.x Ti.sub.1-x Sb.sub.y O.sub.3 (where 0<x<1, 0.0001.ltoreq.y.ltoreq.0.05) is provided herein as well as a method of producing it. The presence of the Sb serves to reduce the leakage current of the film when a voltage is applied.
