Orbit-like trajectory of the vortex core in a magnetic nanodot
D. A. Carvajal, A. Riveros, J. Escrig
In physics, conserved quantities are key to understanding and describing physical phenomena. These conserved quantities are related to Noether's theorem and the Lagrangian descript…
Controlling the nucleation and annihilation of skyrmions with magnetostatic interactions
N. Vidal-Silva, A. Riveros, F. Tejo +2
Skyrmions have become one of the most visited topics during the last decade in condensed matter physics. In this work, and by means of analytical calculations and micromagnetic sim…
Surface anisotropy in a magnetic cylinder induced by the displacement of a vortex core
A. Riveros, D. A. Carvajal, J. Escrig
In this article we investigate the induction of a surface anisotropy due to the displacement of the vortex core in a cylindrical nanostructure. In fact, the effect of the displacem…
Distinct magnetic field dependence of Néel skyrmion sizes in ultrathin nanodots
F. Tejo, A. Riveros, J. Escrig +2
We investigate the dependence of the Néel skyrmion size and stability on perpendicular magnetic field in ultrathin circular magnetic dots with out-of-plane anisotropy and interfaci…
Analytical and numerical phase diagrams for cobalt nanostructures: stability region for a Bloch skyrmion
A. Riveros, N. Vidal-Silva, F. Tejo +1
In this letter we calculate the energies corresponding to the different magnetic phases present in a ferromagnetic cylinder by means of analytical calculations. From the comparison…
Stability of Neel skyrmions in ultra-thin nanodots considering Dzyaloshinskii-Moriya and dipolar interactions
N Vidal-Silva, A Riveros, J Escrig
An analytical expression for the energy of Néel skyrmions in ultra-thin nanodots considering exchange, uniaxial anisotropy, Dzyaloshinskii-Moriya, and dipolar contributions has bee…
