Magnetic-field-induced Anderson localization in orbital selective antiferromagnet BaMnBi
Takuma Ogasawara, Kim-Khuong Huynh, Stephane Yu Matsushita +6
We report a metal-insulator transition (MIT) in the half-filled multiorbital antiferromagnet (AF) BaMnBi that is tunable by a magnetic field perpendicular to the AF sublatt…
Large negative magnetoresistance in BaMnBi antiferromagnet
Takuma Ogasawara, Kim-Khuong Huynh, Time Tahara +7
A very large negative magnetoresistance (LNMR) is observed in the insulating regime of the antiferromagnet BaMnBi when a magnetic field is applied perpendicular to the dire…
Ultrathin film of 3D topological insulators by vapor-phase epitaxy: Surface dominant transport in wide temperature revealed by Seebeck measurement
Stephane Yu Matsushita, Khuong Kim Huynh, Katsumi Tanigaki
Realization of intrinsic surface dominant transport in a wide temperature region for a topological insulators (TIs) is an important frontier research in order to promote the progre…
Itinerant antiferromagnetic BaMnPn's showing both negative and positive magnetoresistances
Kim-Khuong Huynh, Takuma Ogasawara, Keita Kitahara +7
We report the discovery of a novel giant magnetoresistance (GMR) phenomenon in a family of BaMnPn antiferromagnets (Pn stands for P, As, Sb, and Bi) with a parity-time…
Thermoelectric properties of 3D topological insulator: Direct observation of topological surface and its gap opened states
Stephane Yu Matsushita, Khuong Kim Huynh, Harukazu Yoshino +3
We report thermoelectric (TE) properties of topological surface Dirac states (TSDS) in three-dimensional topological insulators (3D-TIs) purely isolated from the bulk by employing…
Large-Area and Transferred High-Quality Three-Dimensional Topological Insulator Bi2-xSbxTe3-ySey Ultrathin Film by Catalyst-Free Physical Vapor Deposition
Ngoc Han Tu, Yoichi Tanabe, Yosuke Satake +4
Uniform and large area synthesis of bulk insulating ultrathin films is an important subject toward applications of a surface of three dimensional topological insulators (3D-TIs) in…
