Heat capacity studies of phase transitions in a series of homologous liquid crystals using the AC heat capacity technique
… developed for organic liquids which utilizes the AC heat capacity technique. It can measure heat capacity changes of 1 part in 104 with a temperature resolution of 0.3 mK. This calorimeter has been used to study the smectic A-nematic phase transition in a series of homologous liquid crystals. In …

Heat capacity measurements of yttrium barium(2)copper(3)oxygen(7-delta) near T(c): Fluctuation effects in a bulk superconductor
"High-resolution ac heat capacity measurements of YBa$\sb2$Cu$\sb3$O$\sb{\rm 7-\delta}$ near the critical temperature are reported and discussed. The samples are high-quality single crystals, several of which display untwinned regions making up at least 50% of the sample mass. The heat capacity …

Critical behavior and transport properties of lanthanum manganite
The resistivity, thermopower, magnetization, and ac heat capacity ofLa0.7Ca0.3Mn03, La0.7(Ca,Pb)0.3Mn03, and Lao.7Sro.3Mn03 single crystals have been measured over a broad temperature range in fields of up to 70 kOe. Below Tc, all three samples exhibit a strong T 2 temperature dependence, …
