We report detailed investigations of the properties of a superconductor obtained by substituting In at the Sn site in the topological crystalline insulator (TCI), SnTe. Transport, magnetization, and heat capacity measurements have been performed on crystals of Sn sub(0.6)In sub(0.4) Te, which is shown to be a bulk superconductor with (ProQuest: Formulae and/or non-USASCII text omitted) at ~4.70(5) K and (ProQuest: Formulae and/or non-USASCII text omitted) at ~3.50(5) K. The upper and lower critical fields are estimated to be mu sub(0)Hc2 (0) = 1.42 (3) T and mu sub(0)Hc1 (0) = 0.90 (3) mT, respectively, while Kappa = 56.4(8) indicates this material is a strongly type-II superconductor.
