Thermal and dielectric methods were applied and applied to characterization the ferrolectrics crystals
already almost one century. In this sense them is possible to call classical. Usually characterization of bulk
crystals assumes some restrictions on the sizes and mass of samples so they cannot be too thin or too
lightweight. These restrictions generate difficulties of an experimental study of the nanostructured
ferroelectrics materials and such materials are to develop more and more every year. In turn, these
difficulties create conditions for improvement of experiments technic.
In the report, the comparative review of thermal and dielectric methods of characterization of the bulk
ferroelectric materials, heterostructures and the ferroelectrics thin films is carried out. The main attention is
paid to methods of measurement of a specific heat and dielectric permittivity of these materials. Both
widely known methods of characterization of a ferroelectric material, and the original methods developed
by authors are considered. In particular, a method of probe heating for thermal characterization and a
thermal noise method for dielectric characterization the ferroelectrics thin films discussed in more detail.
At a material choice, the preference is given to models ferroelectrics crystals and their behavior in the
temperature range including the ferroelectrics phase transition.
