Role of low-frequency vibrations on sound propagation in glasses at intermediate temperature
(American Physical Society, 2000)
We report measurements of the temperature dependence of the sound attenuation and the fractional change in sound velocity for the glass (G) and orientational-glass (OG) phases of polymorphic ethanol. Strikingly similar ...

Square modulated differential thermal analysis
(Elsevier, 2002-12-27)
KMnF3 and DKDP crystals have been studied around their phase transitions using a conduction calorimetry technique where a long periodical square thermal pulse (0.05 K in amplitude) is superposed to a heating or cooling ...
