Self-Consistent Perturbation Theory for Thermodynamics of Magnetic Impurity Systems
arXiv:cond-mat/0510424 · doi:10.1143/JPSJS.75S.256
Abstract
Integral equations for thermodynamic quantities are derived in the framework of the non-crossing approximation (NCA). Entropy and specific heat of 4f contribution are calculated without numerical differentiations of thermodynamic potential. The formulation is applied to systems such as PrFe4P12 with singlet-triplet crystalline electric field (CEF) levels.
