摘要：
We studied the domain structure of thin ferroelectric films from the pyroelectric response to heating by a pulsed laser. Barium-strontium niobate SrxBa1-xNb2O6 (SBN) films grown by plasma spraying on a layer of indium-tin oxide (ITO), which was deposited on a sapphire substrate, were studied. This technique makes it possible to determine the magnitude of the spontaneous polarization of the film and the distribution of the pyroelectric coefficient over the depth of the sample.
