The domain-wall motion driven by a rotating field in a ferrimagnet
Munsu Jin, Ik-Sun Hong, Duck-Ho Kim +2
We theoretically study a ferrimagnetic domain-wall motion driven by a rotating magnetic field. We find that, depending on the magnitude and the frequency of the rotating field, the…
Direct demonstration of topological stability of magnetic skyrmions via topology manipulation
Soong-Geun Je, Hee-Sung Han, Se Kwon Kim +8
Topological protection precludes a continuous deformation between topologically inequivalent configurations in a continuum. Motivated by this concept, magnetic skyrmions, topologic…
Topological waveguide based on metamaterials of magnetic solitons
Gyungchoon Go, Ik-Sun Hong, Seo-Won Lee +2
We theoretically investigate coupled gyration modes of magnetic solitons whose distances to the nearest neighbors are staggered. In a one-dimensional bipartite lattice, analogous t…
Magnetic Skyrmion Field-Effect Transistors
Ik-Sun Hong, Kyung-Jin Lee
Magnetic skyrmions are of considerable interest for low-power memory and logic devices because of high speed at low current and high stability due to topological protection. We pro…
Dzyaloshinskii-Moriya interaction induced extrinsic linewidth broadening of ferromagnetic resonance
Jung Hyun Oh, Ik-Sun Hong, Kyung-Jin Lee
For a thin ferromagnetic film with the Dzyaloshinskii-Moriya interaction (DMI), we derive an expression of the extrinsic ferromagnetic resonance (FMR) linewidth in a quantum mechan…
Detrimental Effect of Interfacial Dzyaloshinskii-Moriya Interaction on Perpendicular Spin-Transfer-Torque Magnetic Random Access Memory
Peong-Hwa Jang, Kyoungmi Song, Seung-Jae Lee +2
Interfacial Dzyaloshinskii-Moriya interaction in ferromagnet/heavy metal bilayers is recently of considerable interest as it offers an efficient control of domain walls and the sta…
