Abstract
The report measurements of the upper critical field, H_(c2), inclined at various angles with respect to the c axis in the heavy-fermion superconductor UPt_3. The angular anisotropy observed near T_(c)=0.53 K cannot be explained quantitatively by presently available theoretical expressions which consider either isotropic or anisotropic pairing. In addition, we find that the anisotropy apparently disappears at T∼200 mK, only to reemerge at lower temperatures with an opposite sense. We have also studied H_(c2) in the basal plane of this hexagonal crystal and find no angular dependence within the limits of our measurements.
