Nanostructured Magnetic Systems

The laboratory’s research focuses primarily on studying how magnetic properties of technological interest are controlledly modified by confining the dimensions of the material to the scale of nanometers in one or more space directions. This includes thin film-type systems, multilayers in which different types of materials alternate (i.e., hybrids), or ordered sets of elements obtained by lithography.

The group’s thin sheet deposition and processing systems allow for combining materials alternatively or obtaining a wide range of magnetic alloys, based on both, transition metals and rare earth elements. This has made possible the study of both magnetic nanostructures of materials with anisotropy in the plane of the substrate, and in systems that present perpendicular magnetic anisotropy.

Thus, some of the most relevant results obtained by the group in recent years refer to aspects as varied as the movement of magnetic domain walls in the magnetization reversal processes in sheets with a nanostructured surface; the control of topological defects such as vortices or magnetic merons that appear in nanostructured and multilayer systems; or the dynamics of superconducting vortices, hybrid systems made up of ordered sets of magnetic nanoelements interacting with superconducting sheets.
