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…

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…
