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, Lucía Gómez-Cruz, Laura Álvaro-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, Joaquín 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…
