摘      要：We study heat transport in a graphene ferromagnet-insulator-superconducting *** is found that the thermal conductance of the graphene ferromagnet-insulator-superconductor(FIS)junction is an oscillatory function of the barrier strength X in the thin-barrier *** gate potential Uo decreases the amplitude of thermal conductance *** the amplitude and phase of the thermal conductance oscillation varies with the exchange energy *** thermal conductance of a graphene FIS junction displays the usual exponential dependence on temperature,reflecting the s-wave symmetry of superconducting graphene.
