Abstract

DC magnetization curves of a single crystal of UPt₃ (T_c = 542 mK) are obtained with the external field parallel and perpendicular to the hexagonal c-axis. The magnetization curves are analyzed to yield the lower critical field H_c1 as a function of temperature and orientation. For both the c-axis and basal plane orientations, H_c1 shows an apparent kink in slope about 150 mK below T_c. This behavior appears to confirm the recently proposed model for the superconducting states in UPt₃ in which a two dimensional order parameter leads to the formation of two distinct superconducting phases.
