Topology is a powerful tool for categorizing magnetization textures by defining a topological index in both two-dimensional (2D) systems, such as thin films or curved surfaces, and in 3D bulk systems. In the emerging field of 3D nanomagnetism, both volume and surface topological numbers must be considered, requiring the identification of a proper global topological […]

We propose the concept of a core-shell composite structure coupled antiparallel via dipolar interaction, as the storage layer in perpendicular-shape-anisotropy magnetic random access memory (PSA MRAM). Benefits compared with a standard PSA MRAM include a reduced write time and the stray field. CoFeB core with a Co shell (height 8 nm; diameters 14 and 20 […]

This joint Phd defense between Université Grenoble Alpes (SPINTEC) and Universidad Complutense de Madrid (IMDEA) will be held in an hybrid mode […]

  We combined chemical synthesis, magnetic microscopy and micromagnetic simulations to provide a comprehensive view of the micromagnetics of chemical modulations in cylindrical nanowires. This sets the ground for their use to investigate the specific aspects of domain-wall dynamics and spin waves in a curvilinear system. Curvilinear and three-dimensional magnetism are a fast-developing field, considering […]
