摘要：
The field versus temperature phase diagram of the magnetic superconductor YbPd2Sn has been determined by electrical resistivity, AC magnetic susceptibility and specific heat. The upper critical field B-c2 is found to be small (0.04 T at T --> 0). Reentrant behavior in the magnetic field implies competition between the superconductivity and antiferromagnetic short-range correlation. Based on a Schottky peak found in the specific heat for B greater than or equal to 0.3 T, the crystalline-field ground state of Yb3+ is confirmed to be Gamma(7). (C) 1998 Elsevier Science B.V.
