Abstract

Abstract: We find that low temperature superconducting phase (LSP) of SrPd2 Sb2 with the CaBe2 Ge2 -type structure at Tc = 1.4 K. Superconducting transition is found at Tc = 1.4 K in electrical resistivity ρ(T) . Specific heat C(T) shows a clear anomaly at Tc = 1.2 K, which shows that superconductivity is of bulk nature. From ρ(T) in several magnetic fields, the upper critical field μ 0 Hc 2 (0) is estimated to be 36 mT, which is strongly suppressed, and is 16.7 times smaller than that of 1.9 K phase.
