Controlled antivortex propagation at bifurcations in reconfigurable NdCo/NiFe racetracks
V. V. Fernandez, A. E. Herguedas-Alonso, C. Fernandez-Gonzalez +7
The controlled propagation of spin textures at bifurcations is a critical challenge for racetrack-based logic devices. Here, we investigate the effect of longitudinal and transvers…
Non-reciprocity and exchange-spring delay of domain-wall Walker breakdown in magnetic nanowires with azimuthal magnetization
Lucía Gómez-Cruz, LucÃa Gómez-Cruz, Laura Ãlvaro-Gómez +19
Domain-wall (DW) motion is a crucial process involved in magnetization reversal, be it under magnetic field or spin-polarized current stimulus. In most cases the DW speed does not…
MARTApp: software for the processing and reconstruction of synchrotron radiation-based magnetic tomographies
A. Estela Herguedas-Alonso, JoaquÃn Gómez Sánchez, Claudia Fernández-González +4
Magnetic vector tomography allows for visualizing the 3D magnetization vector of magnetic nanostructures and multilayers with nanometric resolution. In this work, we present MARTAp…
Tailoring the energy landscape of a Bloch point singularity with curvature
Sandra Ruiz-Gomez, Claas Abert, Pamela Morales-Fernández +14
Topological defects, or singularities, play a key role in the statics and dynamics of complex systems. In magnetism, Bloch point singularities represent point defects that mediate…
