Abstract: We have measured the upper critical fieldH<subscript>C2</subscript>(T) of YBa<subscript>2</subscript>Cu<subscript>3</subscript>O<subscript>7</subscript> (YBCO) thin films in magnetic fields up to 140 T forH applied parallel to thec-axis of the film. The critical field in the zero-temperature limit is 138 T, and the temperature dependence does not fit any simple model.
