Structural Disorder and Magnetic Properties of Geometrically Frustrated Magnets

Explore the intriguing world of geometrically frustrated magnets in this 41-minute conference talk by Rafael S. Freitas from USP, Brazil. Delve into the complex relationship between structural disorder and magnetic properties in these fascinating materials. Begin with an introduction to magnetic frustration and frustrated lattices, focusing on the pyrochlore lattice and its oxides. Examine the dipolar spin ice model and various experimental techniques such as X-ray diffraction and Raman spectroscopy. Analyze phase diagrams, magnetic data, and AC magnetic susceptibility to understand the behavior of these systems. Compare spin glasses models and investigate the concept of spin ice as a Coulomb spin liquid or grassy state. Gain valuable insights into this cutting-edge research presented at the Workshop on Strong Electron Correlations in Quantum Materials: Inhomogeneities, Frustration, and Topology, hosted by ICTP-SAIFR in June 2023.
