Voltage-control of damping constant in magnetic-insulator/topological-insulator bilayers
Takahiro Chiba, Alejandro O. Leon, Takashi Komine
The magnetic damping constant is a critical parameter for magnetization dynamics and the efficiency of memory devices and magnon transport. Therefore, its manipulation by electric…
Elemental topological Dirac semimetal α-Sn with high quantum mobility
Le Duc Anh, Kengo Takase, Takahiro Chiba +3
α-Sn with a diamond-type crystal structure provides an ideal avenue to investigate novel topological properties owing to its rich diagram of topological phases and simple elemental…
Thermoelectric refrigerator based on asymmetric surfaces of a magnetic topological insulator
Takahiro Chiba, Takashi Komine
Thermoelectric (TE) refrigeration such as Peltier cooler enables a unique opportunity in electric energy to directly convert thermal energy. Here, we propose a TE module with both…
Voltage-driven Magnetization Switching via Dirac Magnetic Anisotropy and Spin--orbit Torque in Topological-insulator-based Magnetic Heterostructures
Takahiro Chiba, Takashi Komine
Electric-field control of magnetization dynamics is fundamentally and technologically important for future spintronic devices. Here, based on electric-field control of both magneti…
Giant gate-controlled proximity magnetoresistance in semiconductor-based ferromagnetic/nonmagnetic bilayers
Kosuke Takiguchi, Le Duc Anh, Takahiro Chiba +3
The evolution of information technology has been driven by the discovery of new forms of large magnetoresistance (MR), such as giant magnetoresistance (GMR) and tunnelling magnetor…
