Resistive upper critical fields and anisotropy of an electron-doped infinite-layer cuprate
Abstract
We report a transport study down to 2 K and in high magnetic fields up to 20 T of a highly c-axis-oriented epitaxial thin film of electron-doped "infinite-layer" cuprate superconductor Sr1-xLaxCuO2 with T-c of 26 K. A 16 T magnetic field perpendicular to the ab plane of the film completely suppresses superconductivity, even at the lowest temperature. Perpendicular magnetic fields shift the resistive transition to lower temperatures, without significant broadening, in a way similar to that seen in conventional superconductors. The upper critical field H-c2 perpendicular to(T) exhibits an almost linear temperature dependence. It is shown that electron-doped infinite-layer cuprate presents three-dimensional superconductivity due to a weaker anisotropy (gamma=15) and smaller H-c2 perpendicular to(T) values than the ones of hole-doped cuprates.
