Large-gap magnetic topological heterostructure formed by subsurface incorporation of a ferromagnetic layer

Toru Hirahara, Sergey V. Eremeev, Tetsuroh Shirasawa +17

Inducing magnetism into topological insulators is intriguing for utilizing exotic phenomena such as the quantum anomalous Hall effect (QAHE) for technological applications. While m…

Direct evidence of hidden local spin polarization in a centrosymmetric superconductor LaO $_{0.55}$ F $_{0.45}$ BiS $_{2}$

Shi-Long Wu, Kazuki Sumida, Koji Miyamoto +9

Conventional Rashba spin polarization is caused by the combination of strong spin-orbit interaction (SOI) and spatial inversion asymmetry. However, Rashba- and Dresselhaus-type spi…

Shubnikov-de Haas oscillations in p and n-type topological insulator (Bi $_{x}$ Sb $_{1 - x}$ ) $_{2}$ Te $_{3}$

Ryota Akiyama, Kazuki Sumida, Satoru Ichinokura +4

We show Shubnikov-de Haas oscillations in topological insulator (Bi $_{x}$ Sb $_{1 - x}$ ) $_{2}$ Te $_{3}$ films whose carrier type is p-type (x = 0.29, 0.34) and n-type (x = 0.42). The ph…
