Theory of Magnetic-Texture-Induced Anomalous Hall Effect on the Surface of Topological Insulators
Terufumi Yamaguchi, Ai Yamakage
The anomalous Hall effect is caused by magnetic textures such as skyrmions. We derive an analytical formula of the Hall conductivity on the surface of a topological insulator up to…
Step-like dependence of memory function on pulse width in spintronics reservoir computing
Terufumi Yamaguchi, Nozomi Akashi, Kohei Nakajima +3
Physical reservoir computing is a type of recurrent neural network that applies the dynamical response from physical systems to information processing. However, the relation betwee…
Periodic structure of memory function in spintronics reservoir with feedback current
Terufumi Yamaguchi, Nozomi Akashi, Sumito Tsunegi +3
The role of the feedback effect on physical reservoir computing is studied theoretically by solving the vortex-core dynamics in a nanostructured ferromagnet. Although the spin-tran…
Phase estimation of spin-torque oscillator by nonlinear spin-torque diode effect
Terufumi Yamaguchi, Sumito Tsunegi, Tomohiro Taniguchi
A theoretical analysis is developed on spin-torque diode effect in nonlinear region. An analytical solution of the diode voltage generated from spin-torque oscillator by the rectif…
Synchronization and chaos in a spin-torque oscillator with a perpendicularly magnetized free layer
Terufumi Yamaguchi, Nozomi Akashi, Kohei Naka jima +3
Synchronization and chaos caused by alternating current and microwave field in a spin torque oscillator consisting of a perpendicularly magnetized free layer and an in-plane magnet…
Microscopic theory of magnon-drag electron flow in ferromagnetic metals
Terufumi Yamaguchi, Hiroshi Kohno, Rembert A. Duine
A temperature gradient applied to a ferromagnetic metal induces not only independent flows of electrons and magnons but also drag currents because of their mutual interaction. In t…
