Abstract

We report complex ac magnetic susceptibility measurements of a superconducting transition in very high-quality single-crystal (formula presented) -uranium using microfabricated coplanar magnetometers. We identify an onset of superconductivity at (formula presented) in both the real and imaginary components of the susceptibility which is confirmed by resistivity data. A superconducting volume fraction argument, based on a comparison with a calibration (formula presented) sample, indicates that superconductivity in these samples may be filamentary. Our data also demonstrate the sensitivity of the coplanar micro-magnetometers, which are ideally suited to measurements in pulsed magnetic fields exceeding 100 T.
