Emergence of inductance and capacitance from topological electromagnetism
Yasufumi Araki, Jun'ichi Ieda
Topological electromagnetism owing to nontrivial momentum-space topology of electrons in insulators gives rise to diverse anomalous magnetoelectric responses. While conventional in…
Emergent inductance by dynamical Aharonov-Casher phases
Yuta Yamane, Shunsuke Fukami, Jun'ichi Ieda
We propose a mechanism of inductance operation originating from a dynamical Aharonov-Casher (AC) phase of an electron in ferromagnets. By taking into account spin-orbit coupling ef…
Intrinsic torques emerging from anomalous velocity in magnetic textures
Yasufumi Araki, Jun'ichi Ieda
Momentum-space topology of electrons under strong spin-orbit coupling contributes to the electrically induced torques exerting on magnetic textures insensitively to disorder or the…
Intrinsic and extrinsic tunability of Rashba spin-orbit coupled emergent inductors
Jun'ichi Ieda, Yuta Yamane
The emergent induction of spiral magnets that was proposed [Jpn. J. Appl. Phys. 58, 120909 (2019)] and recently demonstrated [Nature 586, 232 (2020)] is shown to be further extende…
Skyrmion-generated spinmotive forces in inversion broken ferromagnets
Yuta Yamane, Jun'ichi Ieda
We present an analytical study on the spinmotive force (SMF) generated by translational motion of magnetic skyrmion. A SMF refers to an electrical voltage induced by dynamical magn…
Magnetic anisotropy by Rashba spin-orbit coupling in antiferromagnetic thin films
Jun'ichi Ieda, Stewart E. Barnes, Sadamichi Maekawa
Magnetic anisotropy in an antiferromagnet (AFM) with inversion symmetry breaking (ISB) is investigated. The magnetic anisotropy energy (MAE) resulting from the Rashba spin-orbit an…
