Bulk Superconductivity Induced by In-plane Chemical Pressure Effect in Eu0.5La0.5FBiS2-xSex
Gen Jinno, Rajveer Jha, Akira Yamada +6
We have investigated Se substitution effect to superconductivity of an optimally-doped BiS2-based superconductor Eu0.5La0.5FBiS2. Eu0.5La0.5FBiS2-xSex samples with x = 0-1 were syn…
Specific Heat and Electrical Transport Properties of Sn0.8Ag0.2Te Superconductor
Yoshikazu Mizuguchi, Akira Yamada, Ryuji Higashinaka +4
Sn0.8Ag0.2Te is a new superconductor with Tc ~ 2.4 K. The superconducting properties of Sn0.8Ag0.2Te have been investigated by specific heat measurements under magnetic fields. Bul…
Compositional and temperature evolution of crystal structure of new thermoelectric compound LaOBiS2-xSex
Y. Mizuguchi, A. Miura, A. Nishida +7
We examined the crystal structure of the new thermoelectric material LaOBiS2-xSex, whose thermoelectric performance is enhanced by Se substitution, by using powder synchrotron X-ra…
Crystal structure instability of FeSe grains: Formation of non-superconducting phase at the grain surface
Hiroki Izawa, Yuji Tanaka, Yoshikazu Mizuguchi +1
We investigated the magnetization and crystal structure of FeSe polycrystalline samples with various grain sizes. For the samples with large grains, a large magnetic critical curre…
High-Pressure Synthesis and Superconductivity of Ag-doped Topological Crystalline Insulator SnTe (Sn1-xAgxTe with x = 0-0.5)
Yoshikazu Mizuguchi, Osuke Miura
We have synthesized the single-phase polycrystalline samples of Sn1-xAgxTe, Ag-doped topological crystalline insulator SnTe, with a range of x = 0-0.5 using a high-pressure synthes…
Thermoelectric properties of new Bi-chalcogenide layered compounds
Yoshikazu Mizuguchi, Atsuhiro Nishida, Atsushi Omachi +1
The layered Bi-chalcogenide compounds have been drawing much attention as a new layered superconductor family since 2012. Due to the rich variation of crystal structure and constit…
