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…

Giant superconducting diode effect in ion-beam patterned Sn-based superconductor nanowire / topological Dirac semimetal planar heterostructures

Keita Ishihara, Le Duc Anh, Tomoki Hotta +3

Superconductor/topological material heterostructures are intensively studied as a platform for topological superconductivity and Majorana physics. However, the high cost of nanofab…

Growth and characterization of quaternary-alloy ferromagnetic semiconductor (In,Ga,Fe)Sb

Tomoki Hotta, Kengo Takase, Kosuke Takiguchi +3

We study the growth and properties of quaternary-alloy ferromagnetic semiconductor (FMS) (In0.94-x,Gax,Fe0.06)Sb (x = 5% - 30%, Fe concentration is fixed at 6%) grown by low temper…
