Study of the spatial distribution of the polarization in ferroelectric ceramics by means of low frequency sinusoidal thermal waves

Abstract

Abstract A new method for the determination of the distribution of polarization in ferroelectric materials has been developed. It is an intermediate between that of Low Frequency Thermal Waves and the one known as LIMM. This method allows measurements at frequencies in the range of 10−4 Hz to 200 Hz. Experimental results on three different kinds of ferroelectric materials are shown: singlecrystal, ceramic and polymer. This technique can be easily implemented at any laboratory.
