We will study the emergence of complex magnetic order in rare-earth materials and ascertain the role of spin orbit coupling and magnetic exchange. We will aim at manipulating this order, with laser fields, in order to quantify how we can utilize these materials for magnetic memory and low-energy spin transfer. Moreover, we will explore the presence of topological magnons as well as fundamentally new types of quasiparticle excitations, like fractons, in these material systems.
