| Outline of Final Research Achievements |
One of the main motivation of modern research in Condensed Matter is to understand and control the unconventional properties of magnetic materials. Sometimes, the interaction between atoms is "frustrated", unable to accommodate all atoms at the same time, creating a competition at the microscopic level. An increasingly large variety of magnets appear to be "frustrated", each of them with their own exotic peculiarities. Our motivation in this project has been to go beyond the traditional theoretical models of magnetic frustration considering relevant, more complex, interactions. We have found, among other things, a surprisingly rich physics out of equilibrium in a family of rare-earth crystals, and low-temperature magnetic phases where microscopic local rules lead to extended fractal structures, opening new directions on how to control topological defects in magnets.
