Transport properties in normal metal Bi2Pd3S2 and superconducting Bi2Pd3Se2 Sakamoto, Takeshi 19557 Wakeshima, Makoto 19558 Hinatsu, Yukio 19559 Matsuhira, Kazuyuki 20843 松平, 和之 40312342 マツヒラ, カズユキ 6701529054 0000-0001-9185-0016 82 The transport properties of the parkerite-related compounds Bi2Pd3X2 (X=S,Se) were studied. The electrical resistivities of both compounds show typical metallic behavior up to 400 K. Resistivity and specific heat measurements at low temperatures reveal that Bi2Pd3Se2 is superconducting below 1 K. On the other hand, Bi2Pd3S2 does not show a bulk superconducting transition down to 0.35 K. In the normal state, the electronic specific heat coefficient γ and the Debye temperature θD are found to be 5.9 mJ/mol K2 and 170 K, respectively for Bi2Pd3S2, and 8.3 mJ/mol K2 and 150 K, respectively for Bi2Pd3Se2. In the superconducting state for Bi2Pd3Se2, the upper critical field at zero temperature for Bi2Pd3Se2 is 290 mT. From the electronic specific heat in the superconducting temperature range, it was found that Bi2Pd3Se2 belongs to an s-wave weakcoupling superconductor. journal article Published by the American Physical Society through the American Institute of Physics 2008-07-09 VoR application/pdf Physical review.
