摘要：

An alternative method to obtain hysteresis loops for ferroelectric thin films is described that overcomes the drawbacks of the classical methods. In this method, a pulsed signal, obtained by mixing a sinusoidal voltage of low frequency with a square voltage of variable period and width, is applied to a (Pb0.76Ca0.24)TiO3 thin film. Electric field is applied to the sample for a short time and so, contribution of extra charges to the hysteresis loops is very small. The experimental loops measured only need a small compensation.
