Spin-Transfer Torque on Curved Surfaces: A Generalized Thiele Formalism
J. I. Costilla, M. Castro, K. V. Yershov +3
Curvature is a highly relevant parameter when considering nanostructures, favoring the stability and affecting the dynamics of magnetic textures. In this work, we address the spin-…
Tuning domain wall oscillation frequency in bent nanowires through a mechanical analogy
G. H. R. Bittencourt, V. L. Carvalho-Santos, D. Altbir +2
In this work, we present a theoretical model for domain wall (DW) oscillations in a curved magnetic nanowire with a constant curvature under the action of a uniaxial magnetic field…
Chiral spin-transfer torque induced by curvature gradient
G. H. R. Bittencourt, M. Castro, A. S. Nunez +3
This work analyzes the propagation of a transverse domain wall (DW) motion under the action of an electric current along a nanowire (NW) with a curvature gradient. Our results evid…
Magnonic Hall Effect and Magnonic Holography of Hopfions
Carlos Saji, Roberto E. Troncoso, Vagson L. Carvalho-Santos +2
Hopfions are localized and topologically non-trivial magnetic configurations that have received considerable attention in recent years. Through a micromagnetic approach, we analyze…
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…
