Temperature profile of the Thomson-effect-induced heat release/absorption in junctionless single conductors
Takahiro Chiba, Ryo Iguchi, Takashi Komine +2
The Thomson effect induces heat release or absorption under the simultaneous application of a charge current and a temperature gradient to conductors. Here, we theoretically invest…
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…
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…
Tight-binding theory of surface spin states on bismuth thin films
Kazuo Saito, Hirokatsu Sawahata, Takashi Komine +1
The surface spin states for bismuth thin films were investigated using an tight-binding model. The model explains the experimental observations using angle-resolved photoemi…
