Scalar Spin Chirality Hall Effect
Gyungchoon Go, Durga Prasad Goli, Nanse Esaki +2
The scalar spin chirality, which characterizes the fundamental unit of noncoplanar spin structures, plays an important role in rich chiral physics of magnetic materials. In particu…
Emergence of stable meron quartets in twisted magnets
Kyoung-Min Kim, Gyungchoon Go, Moon Jip Park +1
The investigation of twist engineering in easy-axis magnetic systems has revealed the remarkable potential for generating topological spin textures, such as magnetic skyrmions. Her…
Intrinsic Magnon Orbital Hall Effect in Honeycomb Antiferromagnets
Gyungchoon Go, Daehyeon An, Hyun-Woo Lee +1
We theoretically investigate the transport of magnon orbitals in a honeycomb antiferromagnet. We find that the magnon orbital Berry curvature is finite even without spin-orbit coup…
Alternative understanding of the skyrmion Hall effect based on one-dimensional domain wall motion
Kyoung-Woong Moon, Jungbum Yoon, Changsoo Kim +4
A moving magnetic skyrmion exhibits transverse deflection. This so-called skyrmion Hall effect has been explained by the Thiele equation. Here, we provide an alternative interpreta…
Interaction of gapless spin waves and a domain wall in an easy-cone ferromagnet
Wooyon Kim, Se Kwon Kim
We theoretically study the interaction of spin waves and a domain wall in a quasi-one-dimensional easy-cone ferromagnet. The gapless spin waves on top of a domain wall are found to…
Magnon dynamics in a Skyrmion-textured domain wall of antiferromagnets
Seungho Lee, Kouki Nakata, Oleg Tchernyshyov +1
We theoretically investigate the interaction between magnons and a Skyrmion-textured domain wall in a two-dimensional antiferromagnet and elucidate the resultant properties of magn…
