Spin waves scattering on a Bloch point

R. G. Elías, V. L. Carvalho-Santos, A. S. Núñez +1

We show that, after a transformation, the dynamics of linear perturbations (spin waves) around a singular Bloch point soliton is formally equivalent to a quantum system of an elect…

Curvature-induced changes in the magnetic energy of vortices and skyrmions in paraboloidal nanoparticles

V. L. Carvalho-Santos, R. G. Elias, J. M. Fonseca +1

Curvature effects are important for a proper description of the properties of magnetic systems. In this paper the exchange and dipolar energy of vortices on a paraboloidal shell is…

Topological magnetic solitons on a paraboloidal shell

P. S. C. Vilas-Boas, R. G. Elias, D. Altbir +2

We study the influence of curvature on the exchange energy of skyrmions and vortices on a paraboloidal surface. It is shown that such structures appear as excitations of the Heisen…

Stability of skyrmions on curved surfaces in the presence of a magnetic field

V. L. Carvalho-Santos, R. G. Elias, D. Altbir +1

We study the stability and energetics associated to skyrmions appear- ing as excitations on curved surfaces. Using a continuum model we show that the presence of cylindrically radi…
