Show affiliationsWe investigate an anomalously enhanced jump of the electronic specific heat at the superconducting transition point observed in CeCoIn5 within the fluctuation-exchange approximation. The strong antiferromagnetic spin fluctuation leads to strong-coupling superconductivity with a relatively high transition temperature. Simultaneously, the jump of the specific heat becomes large. This tendency also becomes stronger as the antiferromagnetic spin fluctuation becomes stronger.
