Transport in magnetic-topological-insulator nanoribbons containing multiple superconductor-proximitized sectors
Javier Osca, Sungguen Ryu, Rosa López +1
Transport in devices with multiple proximitized sectors depends heavily on the complex phases of the pairing gaps of those sectors. We investigate magnetic topological insulator na…
Electrostatic gating and the interference of chiral Majoranas in thin slabs of magnetic topological insulators
Javier Osca, Llorenç Serra
We study the interference of chiral Majoranas in a magnetic topological insulator thin slab having a grounded section proximity coupled to a superconductor and another section unde…
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.…
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…
