Title: Superconducting properties of Rh 9 In 4 S 4 single crystals

The synthesis and crystallographic, thermodynamic, and transport properties of single crystalline Rh 9In 4S 4 were studied. The resistivity, magnetization, and specific heat measurements all clearly indicate bulk superconductivity with a critical temperature, T c~2.25 K. The Sommerfeld coefficient γ and the Debye temperature (ΘD) were found to be 34 mJ mol –1 K –2 and 217 K, respectively. The observed specific heat jump, ΔC/γT c=1.66, is larger than the expected BCS weak coupling value of 1.43. Ginzburg-Landau (GL) ratio of the low-temperature GL-penetration depth, λ GL≈5750 Å, to the GL-coherence length, ξ GL≈94 Å, is large: κ ~60. However, we observed a peak effect in the resistivity measurement as a function of both temperature and magnetic field.
