Superconductivity in Single-Crystal YIn3
arXiv:1112.3083 · doi:10.1016/j.ssc.2011.12.040
Abstract
We measure the superconducting transition of YIn by resistivity, susceptibility, and specific heat. Despite using high-quality single-crystal samples, the transitions detected by the three techniques are shifted from each other in temperature, suggesting a region of filamentary superconductivity. We discuss the possible implications for filamentary superconductivity in unconventional superconductors.
