Giant odd-parity magnetoresistance from proximity-induced topological states
Tomoki Hotta, Le Duc Anh, Takahiro Chiba +2
Magnetoresistance typically exhibits even symmetry with respect to the magnetic field, owing to time reversal symmetry (TRS) as dictated by Onsager reciprocity relations. However,…

Topological surface states induced by the magnetic proximity effect
Soichiro Fukuoka, Le Duc Anh, Masayuki Ishida +4
The combination of magnetism and topological properties in one material platform is attracting significant attention due to the potential of realizing low power consumption and err…

Allotropic transition of Dirac semimetal α-Sn to superconductor β-Sn induced by irradiation of focused ion beam
Kohdai Inagaki, Keita Ishihara, Tomoki Hotta +9
Diamond-type structure allotrope α-Sn is attracting much attention as a topological Dirac semimetal (TDS). In this study, we demonstrate that α-Sn undergoes a phase transition to a…
