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…
Edge-Soliton-Mediated Vortex-Core Reversal Dynamics
Ki-Suk Lee, Myoung-Woo Yoo, Youn-Seok Choi +1
We report a new reversal mechanism of magnetic vortex cores in nanodot elements driven by out-of-plane currents, occurring through two coupled edge-solitons via dynamic transformat…
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…
