Abstract
The (Formula presented) phase diagram for thin film (Formula presented) with B parallel to the superconducting layers has been constructed from GHz transport measurements to 150 T. Up to 110 T the upper critical field is found to be linear in T and in remarkable agreement with extrapolation of the longstanding result of Welp et al. arising from magnetization measurements to 6 T. Beyond this a departure from linear behavior occurs at (Formula presented) consistent with previous low-temperature data. Evidence for a transition from a high-(Formula presented) regime dominated by orbital effects, to a low-(Formula presented) regime, where paramagnetic limiting drives the quenching of superconductivity, is seen.
