Analysis of the Critical Exponents for Imidazolium Perchlorate Close to the Phase Transition Temperature of 373 K

Abstract

The critical exponents 𝛼, 𝛽 and 𝛾 for the specific heat, polarization and the dielectric susceptibility, respectively, have been deduced below to the phase transition temperature of TC = 373 K for the Imidazolium Perchlorate (Im-ClO4) crystal. The analysis of the critical behavior of the specific heat has been carried out using the compressible Ising model, while analysis of the polarization and the dielectric susceptibility has been performed in terms of the power-law equations. Our results show that the Rushbrooke inequality is satisfied for the Im-ClO4 crystal below the phase transition temperature of TC = 373 K.
