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…
Bistability of vortex core dynamics in a single perpendicularly magnetized nano-disk
Grégoire De Loubens, A. Riegler, B. Pigeau +10
Microwave spectroscopy of individual vortex-state magnetic nano-disks in a perpendicular bias magnetic field, , is performed using a magnetic resonance force microscope (MRFM).…
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…
Origin of the increased velocities of domain wall motions in soft magnetic thin-film nanostripes beyond the velocity-breakdown regime
Sang-Koog Kim, Jun-Young Lee, Youn-Seok Choi +2
It is known that oscillatory domain-wall (DW) motions in soft magnetic thin-film nanostripes above the Walker critical field lead to a remarkable reduction in the average DW veloci…
