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…
