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…
Detecting quadrupole: a hidden source of magnetic anisotropy for Manganese alloys
Jun Okabayashi, Yoshio Miura, Yohei Kota +3
Mn-based alloys exhibit unique properties in the spintronics materials possessing perpendicular magnetic anisotropy (PMA) beyond the Fe and Co-based alloys. It is desired to figure…
Dynamics of slender monopoles and anti-monopoles in non-Abelian superconductor
Masato Arai, Filip Blaschke, Minoru Eto +1
Low energy dynamics of magnetic monopoles and anti-monopoles in the U(2) gauge theory is studied in the Higgs (non-Abelian superconducting) phase. The monopoles in this superconduc…
