Strategic Focus

Study of the magnetic properties of nanostructured systems. Monte Carlo simulation and Micromagnetism.

Research Lines and/or Areas

Although there are no established research lines at this time, the evolution of the G+ and the generation of new lines of research in this period that are consistent with specific needs are intended. Some of them could be related in the type of systems to be studied (e.g., ferrofluids, clusters, or biomolecules).
