DC magnetization curves of a single crystal of UPt3 (Tc = 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 Hc1 as a function of temperature and orientation. For both the c-axis and basal plane orientations, Hc1 shows an apparent kink in slope about 150 mK below Tc. 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.
