Abstract

A new method for analyzing second-order phase transitions is presented and applied to the polaronic system La0.7_{0.7}Ca0.3_{0.3}MnO3_{3}. It utilizes heat capacity and thermal expansion data simultaneously to correctly predict the critical temperature's pressure dependence. Analysis of the critical phenomena reveals second-order behavior and an unusually large heat capacity exponent.
