Emergent impedance due to antiferromagnetic domain wall dynamics
Yuta Yamane, Jotaro J. Nakane, Yasufumi Araki +1
We theoretically investigate emergent impedance induced by domain-wall dynamics in antiferromagnets. Emergent impedance, arising from a combined action of spin-transfer torque and…
Realization of a universal topological waveguide by tuning adiabatic geometry
Keita Funayama, Jotaro J. Nakane, Ai Yamakage
Quantum valley Hall-based topological phases have been attracting attention across diverse fields as a robust platform for wave guidance due to their high compatibility with engine…
Quantum sensing with duplex qubits of silicon vacancy centers in SiC at room temperature
Kosuke Tahara, Shin-ichi Tamura, Haruko Toyama +4
The silicon vacancy center in Silicon Carbide (SiC) provides an optically addressable qubit at room temperature in its spin- electronic state. However, optical spin in…
Topological spin Hall effect in antiferromagnets driven by vector Néel chirality
Kazuki Nakazawa, Koujiro Hoshi, Jotaro J. Nakane +2
Spin Hall effect of spin-texture origin is explored theoretically for antiferromagnetic (AF) metals. It is found that a vector chirality formed by the Néel vector gives rise to a t…
Current-Induced Spin-Wave Doppler Shift in Antiferromagnets
Jotaro J. Nakane, Hiroshi Kohno
We theoretically study the spin dynamics in antiferromagnets (AFs)under the influence of an electric current. We identify two different sources of spin-transfer torques that stem f…
Microscopic Calculation of Spin Torques in Textured Antiferromagnets
Jotaro J. Nakane, Hiroshi Kohno
A microscopic calculation is presented for the spin-transfer torques (STT) and damping torques in metallic antiferromagnets (AF). It is found that the sign of the STT is opposite t…
Magnetic-Field-Driven Antiferromagnetic Domain Wall Motion
Jotaro J. Nakane, Hiroshi Kohno
We theoretically study the antiferromagnetic domain wall motion actuated by an inhomogeneous external magnetic field. The Lagrangian and the equations of motion of antiferromagneti…
