Abstract
We have recently shown a possible coexistence of superconductivity and magnetism in the Sc5−xDyxIr4Si10 system from susceptibility (χ) and resistivity (ρ) measurements. In this paper, we present heat-capacity (Cp) data for the same system which establishes the bulk nature of antiferromagnetic ordering in Dy5Ir4Si10 and the coexistence of bulk superconductivity and magnetism in Sc3.5Ir1.5Si10. Our heat-capacity data on Dy samples show considerable contribution from the Schottky effect due to the crystal fields and we have proposed a model which fits well to the χ and Cp data of all the Dy samples with the same crystal field parameters.
