“Ferromagnets, antiferromagntes and magnets beyond”

Abstract:

The ferromagnetic ground state is an exact solution to the Heisenberg model, but no simple solution exists for antiferromagnets. Nature provides us with many more structures and interactions with complex magnetic order, and in some cases quantum fluctuations have a dominant role in the macroscopic properties. We will review a few unusual magnetic materials, and we will discuss a new way of doing electron spin resonance for the study of the elementary excitations in these systems.
