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…
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…
Interaction between magnetic vortex cores in a pair of nonidentical nanodisks
J. P. Sinnecker, H. Vigo-Cotrina, F. Garcia +2
Interacting magnetic nanoobjects constitute one key component for many proposed spintronic devices, from microwave nano-oscillators to magnetic memory elements. For this reason, th…
Effect of perpendicular uniaxial anisotropy on the annihilation fields of magnetic vortices
E. R. P. Novais, S. Allende, D. Altbir +3
The magnetic vortex structure, that is present in several nanoscopic systems, is stable and can be manipulated through the application of a magnetic field or a spin polarized curre…
Magnetic vortex echoes: application to the study of arrays of magnetic nanostructures
F. Garcia, J. P. Sinnecker, E. R. P. Novais +1
We propose the use of the gyrotropic motion of vortex cores in nanomagnets to produce a magnetic echo, analogous to the spin echo in NMR. This echo occurs when an array of nanomagn…
Properties of magnetic nanodots with perpendicular anisotropy
E. R. P. Novais, P. Landeros, A. G. S. Barbosa +3
Nanodots with magnetic vortices have many potential applications, such as magnetic memories (VRAMs) and spin transfer nano-oscillators (STNOs). Adding a perpendicular anisotropy te…
