Anisotropic upper critical field in the van der Waals superconducting quasicrystal (Ta $_{0.7}$ Nb $_{0.3}$ ) $_{1.6}$ Te

Koki Kasai, Yuki Tokumoto, Taichi Terashima +2

We investigated the upper critical field of a large single grain of the Nb-substituted van der Waals layered quasicrystal (Ta $_{0.7}$ Nb $_{0.3}$ ) $_{1.6}$ Te. The sample exhibits a sh…

Topological delocalization against Anderson localization observed in Bi-doped PbSb2Te4 disordered topological insulator

Yuya Hattori, Koichiro Yaji, Keisuke Sagisaka +6

We experimentally investigate the tendency of localization in the bulk and the topological surface states in topological insulators Pb(Bi1-xSbx)2Te4 (x=0.793-0.818) through detaile…

Large Rashba spin-orbit coupling in metallic SrTaO $_{3}$ thin films

Hikaru Okuma, Yumiko Katayama, Fukunobu Kadowaki +2

Epitaxial thin films of SrTaO $_{3}$ with thickness ( $t$ ) smaller than 74 nm were successfully fabricated on an insulator (LaAlO $_{3}$ ) $_{0.3}$ (Sr $_{2}$ AlTaO $_{6}$ ) $_{0.7}$ substrate. Films…

Anomalous upper critical field in the quasicrystal superconductor Ta $_{1.6}$ Te

Taichi Terashima, Yuki Tokumoto, Kotaro Hamano +3

Superconductivity in quasicrystals poses a new challenge in condensed matter physics. We measured the resistance and ac magnetic susceptibility of a Ta $_{1.6}$ Te dodecagonal quasic…
