Abstract
In this work, we show the highly correlated nature of the superconductor Rh17S15 via transport, magnetization and heat capacity measurements. In particular, we will discuss resistivity, susceptibility, heat-capacity and upper critical field studies on a polycrystalline Rh17S15 sample which exhibits superconductivity below 5.4 K. Detailed studies suggest that the superconductivity in this compound arises from strongly correlated charge carriers presumably due to the high density of states of Rh d-bands at the Fermi level. Moreover, the Hall coefficient shows a sign change and increases at low temperature before the sample becomes a superconductor below 5.4 K.
