Single transition PrOs<sub>4</sub>Sb<sub>12</sub> single crystals under strain
ORAL
Abstract
The heavy-fermion PrOs4Sb12 exhibits unconventional superconductivity below 1.85K [1]. Earlier work observed two superconducting transitions and found time reversal symmetry breaking [2, 3],- which has long hinted at the presence of multicomponent superconductivity. Here, we demonstrate the extrinsic nature of the PrOs4Sb12 double transition by conducting a series of transport, thermodynamic, and uniaxial strain measurements on single crystals with different degrees of homogeneity. Our results support the presence of single component superconductivity and impose further constraints on the symmetry of the order parameter.
