Skyrmions in coupled spin torque nano-oscillator structures
H. Vigo-Cotrina, A. P. Guimarães
In the present work, using micromagnetic simulation, we show that the magnetic coupling effect plays a very important role in the process of creation of skyrmions in a coupled syst…
Writing and storing information in an array of magnetic vortex nanodisks using their azimuthal modes
H. Vigo-Cotrina, A. P. Guimarães
The switching of a vortex core of a single disk in an array of a multilayer system is investigated by micromagnetic simulation. We found that the perpendicular uniaxial anisotropy…
Micromagnetic study of skyrmion stability in confined magnetic structures with perpendicular anisotropy
R. L. Novak, F. Garcia, E. R. P. Novais +2
Skyrmions are emerging topological spin structures that are potentially revolutionary for future data storage and spintronics applications. The existence and stability of skyrmions…
Single array of magnetic vortex disks uses in-plane anisotropy to create different logic gates
H. Vigo-Cotrina, A. P. Guimarães
Using micromagnetic simulation, we show that in-plane uniaxial magnetic anisotropy (IPUA) can be used to obtain FAN-OUT, AND and OR gates in an array of coupled disks with magnetic…
Controlling energy transfer time between two coupled magnetic vortex-state disks
H. Vigo-Cotrina, A. P. Guimarães
The influence of the in-plane uniaxial anisotropy (IPUA) in the mutual energy transfer time () between two identical coupled nanodisks was studied. Using an analytical dipolar m…
Indirect switching of vortex polarity through magnetic dynamic coupling
G. B. M. Fior, E. R. P. Novais, J. P. Sinnecker +2
Magnetic vortex cores exhibit a gyrotropic motion, and may reach a critical velocity, at which point they invert their z-component of the magnetization. We performed micromagnetic…
