Vortex dynamics in confined stratified conditions
Farkhad G. Aliev, Juan F. Sierra, Ahmad A. Awad +6
We report on linear spin dynamics in the vortex state of the Permalloy dots subjected to stratified (magnetic) field. We demonstrate experimentally and by simulations the existence…
Criterion for transformation of transverse domain wall to vortex or antivortex wall in soft magnetic thin-film nanostripes
Youn-Seok Choi, Sang-Koog Kim, Jun-Young Lee +3
We report on the criterion for the dynamic transformation of the internal structure of moving domain walls (DWs) in soft magnetic thin-film nanostripes above the Walker threshold f…
Layer-by-layer growth and growth-mode transition of SrRuO3 thin films on atomically flat single-terminated SrTiO3 (111) surfaces
Jaewan Chang, Yoon-Seok Park, Jong-Woo Lee +1
We report on growth-mode transitions in the growth of SrRuO3 thin films on atomically flat Ti4+ single-terminated SrTiO3 (111) substrates, investigated by reflection high-energy el…
Physical Origin and Generic Control of Magnonic Band Gaps of Dipole-Exchange Spin Waves in Width-Modulated-Nanostrip Waveguides
Ki-Suk Lee, Dong-Soo Han, Sang-Koog Kim
We report, for the first time, on a novel planar structure of magnonic-crystal waveguides, made of a single magnetic material, in which the allowed and forbidden bands of propagati…
Dynamic origin of azimuthal modes splitting in vortex-state magnetic dots
Konstantin Y. Guslienko, Andrei N. Slavin, Vasyl Tiberkevich +1
A spin wave theory explaining experimentally observed frequency splitting of dynamical excitations with azimuthal symmetry of a magnetic dot in a vortex ground state is developed.…
Universal criterion and phase diagram for switching a magnetic vortex core in soft magnetic nanodots
Ki-Suk Lee, Sang-Koog Kim, Young-Sang Yu +4
The universal criterion for ultrafast vortex-core switching between the up- and down-core bistates in soft magnetic nanodots was investigated by micromagnetic simulations along wit…
