Torque field and skyrmion movement by spin transfer torque in a quasi-2d interface in presence of strong spin-orbit interaction
Javier Osca, Bart Sorée
We investigate the torque field and skyrmion movement at an interface between a ferromagnet hosting a skyrmion and a material with strong spin-orbit interaction. We analyze both se…
Fabry-Pérot interferometry with gate-tunable 3D topological insulator nanowires
Javier Osca, Kristof Moors, Bart Sorée +1
Three-dimensional topological insulator (3D TI) nanowires display various interesting magnetotransport properties that can be attributed to their spin-momentum-locked surface state…
Skyrmion elongation, duplication and rotation by spin-transfer torque under spatially varying spin current
Floris van Duijn, Javier Osca, Bart Sorée
The effect of the spatially varying spin current on a skyrmion is numerically investigated. It is shown that an inhomogeneous current density induces an elongation of the skyrmion.…
Confined magnetoelastic waves in thin waveguides
Frederic Vanderveken, Jeroen Mulkers, Jonathan Leliaert +5
The characteristics of confined magnetoelastic waves in nanoscale ferromagnetic magnetostrictive waveguides have been investigated by a combination of analytical and numerical calc…
Tanh-sinh quadrature for single and multiple integration using floating-point arithmetic
Joren Vanherck, Bart Sorée, Wim Magnus
The problem of estimating single- and multi-dimensional integrals, with or without end-point singularities, is prevalent in all fields of scientific research, and in particular in…
Skyrmion spin transfer torque due to current confined in a nanowire
Javier Osca, Bart Sorée
In this work we compute the torque field present in a ferromagnet in contact with a metallic nanowire when a skyrmion is present. If the nanowire is narrow enough the current is ca…
2D ferromagnetism at finite temperatures under quantum scrutiny
Joren Vanherck, Cihan Bacaksiz, Bart Sorée +2
Recent years have seen a tremendous rise of two-dimensional (2D) magnetic materials, several of which verified experimentally. However, most of the theoretical predictions to date…
Excitation and propagation of spin waves in non-uniformly magnetized waveguides
Frederic Vanderveken, Hasnain Ahmad, Marc Heyns +3
The characteristics of spin waves in ferromagnetic waveguides with nonuniform magnetization have been investigated for situations where the shape anisotropy field of the waveguide…
Theoretical study of scattering in graphene ribbons in the presence of structural and atomistic edge roughness
Kristof Moors, Antonino Contino, Maarten L. Van de Put +4
We investigate the diffusive electron-transport properties of charge-doped graphene ribbons and nanoribbons with imperfect edges. We consider different regimes of edge scattering,…
An envelope function formalism for lattice-matched heterostructures
Maarten L. Van de Put, William G. Vandenberghe, Wim Magnus +1
The envelope function method traditionally employs a single basis set which, in practice, relates to a single material because the matrix elements are generally only kno…
Resistivity scaling model for metals with conduction band anisotropy
Miguel De Clercq, Kristof Moors, Kiroubanand Sankaran +5
It is generally understood that the resistivity of metal thin films scales with film thickness mainly due to grain boundary and boundary surface scattering. Recently, several exper…
The Miniband Alignment Field-Effect Transistor: a superlattice-based steep-slope nanowire FET
Maarten Thewissen, Bart Sorée, Wim Magnus
This work investigates energy filtering in nanowires, where pass and stopbands are obtained by including superlattices in the wire. When a pair of such superlattices is placed in s…
Resistivity scaling in metallic thin films and nanowires due to grain boundary and surface roughness scattering
Kristof Moors, Bart Sorée, Wim Magnus
A modeling approach, based on an analytical solution of the semiclassical multi-subband Boltzmann transport equation, is presented to study resistivity scaling in metallic thin fil…
Inter-ribbon tunneling in graphene: an atomistic Bardeen approach
Maarten L. Van de Put, William G. Vandenberghe, Bart Sorée +2
A weakly coupled system of two crossed graphene nanoribbons exhibits direct tunneling due to the overlap of the wavefunctions of both ribbons. We apply the Bardeen transfer Hamilto…
