Opis

Modulation Calorimetry reviews modulation techniques for measuring specific heat, thermal expansivity, temperature derivative of resistance, thermopower, and spectral absorptance. Owing to the periodic nature of the temperature oscillations, high sensitivity and excellent temperature resolution are peculiar to all these methods. The monograph presents the various methods of the modulation and of measuring the temperature oscillations. Important applications of the modulation techniques for studying physical phenomena in solids and liquids are considered in depth (equilibrium point defects, phase transitions, superconductors, liquid crystals, biological materials, relaxation phenomena in specific heat, and more).
