Wave modes of collective vortex gyration in dipolar-coupled-dot-array magnonic crystals
Dong-Soo Han, Andreas Vogel, Hyunsung Jung +7
Lattice vibration modes are collective excitations in periodic arrays of atoms or molecules. These modes determine novel transport properties in solid crystals. Analogously, in per…
Normal modes of coupled vortex gyration in two spatially separated magnetic nanodisks
Ki-Suk Lee, Hyunsung Jung, Dong-Soo Han +1
We found from analytical derivations and micromagnetic numerical simulations that there exist two distinct normal modes in apparently complex vortex gyrotropic motions in two dipol…
Memory-bit selective recording in vortex-core cross-point architecture
Young-Sang Yu, Hyunsung Jung, Ki-Suk Lee +2
In our earlier work [Appl. Phys. Lett. 92, 022509 (2008)], we proposed nonvolatile vortex random access memory (VRAM) based on the energetically stable twofold ground state of vort…
Tunable energy transfer between dipolar-coupled magnetic disks by stimulated vortex gyration
Hyunsung Jung, Ki-Suk Lee, Dae-Eun Jeong +9
A wide variety of coupled harmonic oscillators exist in nature1. Coupling between different oscillators allows for the possibility of mutual energy transfer between them2-4 and the…
Polarization-selective vortex-core switching by orthogonal Gaussian-pulse currents
Young-Sang Yu, Ki-Suk Lee, Hyunsung Jung +6
We experimentally demonstrate low-power-consumption vortex-core switching in magnetic nanodisks using tailored rotating magnetic fields that are produced with orthogonal and unipol…
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…
