Ultrahigh efficient spin-orbit torque magnetization switching in all-sputtered topological insulator - ferromagnet multilayers
Tuo Fan, Nguyen Huynh Duy Khang, Soichiro Nakano +1
Spin-orbit torque (SOT) magnetization switching of ferromagnets with large perpendicular magnetic anisotropy has a great potential for the next-generation non-volatile magnetoresis…
Large magnetoresistance and spin-dependent output voltage in a lateral MnGa/GaAs/MnGa spin-valve device
Koki Chonan, Nguyen Huynh Duy Khang, Masaaki Tanaka +1
We investigated the spin-dependent transport properties of a lateral spin-valve device with a 600 nm-long GaAs channel and ferromagnetic MnGa electrodes with perpendicular magnetiz…
Zero-field topological Hall effect in BiSb/MnGa bi-layers as a signature of ground-state skyrmions at room temperature
Nguyen Huynh Duy Khang, Tuo Fan, Pham Nam Hai
We observe the signature of zero-field ground-state skyrmions in BiSb topological insulator / MnGa bi-layers by using the topological Hall effect (THE). We observe a large critical…
Origin of the giant spin Hall effect in BiSb topological insulator
Takanori Shirokura, Kenichiro Yao, Yugo Ueda +1
The giant spin Hall effect (SHE) at room temperature is one of the most attractive feature of topological insulators (TIs) for applications to nano-scale spin devices. Its origin,…
Recent Progress in III-V based ferromagnetic semiconductors: Band structure, Fermi level, and tunneling transport
Masaaki Tanaka, Shinobu Ohya, Pham Nam Hai
Spin-based electronics or spintronics is an emerging field, in which we try to utilize spin degrees of freedom as well as charge transport in materials and devices. While metal-bas…
