A new class of materials called Topological Crystalline Insulator(TCI) has been recently proposedtheoretically and subsequently, SnTe has been discovered to exhibit all the requiredcharacteristics of this state. For levels of In substitution (x~0.4), SnTe is a superconductor with atransition temperature of ~4.5K. The discovery of these materials marks an important step in ourunderstanding of the superconducting state arising out of a TI material. We propose to investigatethe superconducting state of a series of samples, Sn1-xInxTe (x= 0.38, 0.40, 0.41, 0.45) using the MuSR instrument. The understanding of the pairing mechanism in this superconductor has implications on the understanding of a new class of materials, namely Topological Crystalline Superconductors.
