Puzzling evidence for surface superconductivity in the layered dichalcogenide Cu${}_{10\%}$TiSe${}_2$

F. Levy-Bertrand, B. Michon, J. Marcus +4

We report on specific heat and magnetotransport measurements performed on superconducting Cu${}_{10\%}$TiSe${}_2$ single crystals. We show that superconductivity persists in transport…
