Abstract

Measurements of the upper critical magnetic field Hc2 of single-crystal URu2Si2 are reported for fields H8 T and temperatures T0.5 K. Hc2 is strongly anisotropic and exhibits pronounced positive curvature for Ha in the tetragonal basal plane. These features can be explained using a theoretical model that assumes a multicomponent superconducting order parameter that is strongly coupled to the antiferromagnetic moment.
