Abstract
The choice of a method to periodically heat the sample depends on its shape and electrical conductivity, and on the temperature range of the measurements. At high temperatures, direct electric heating or electron bombardment are preferable for conducting samples. In studies of nonconducting samples, separate resistive heaters or modulated-light heating should be used. Various methods of the heating provide different accuracy. For example, the modulated-light heating is usable, where there is no need to accurately determine absolute values of the specific heat. No data on heating-power oscillations are necessary for modulation measurements of thermal expansivity, temperature derivative of resistance, and thermopower.
