Structural and Magnetic Investigations of Cs₂AgF₄ and Its Doped Derivatives

This thesis describes the structural and magnetic properties of solid state silver fluorides such as Cs₂AgF₄ and its doped derivatives. A wide range of techniques such as X-ray and neutron diffraction, susceptibility measurements and inelastic neutron scattering experiments are used to characterize these materials. Silver fluorides are important given their strongly correlated magnetic behavior and the potential to discover a new class of high T_C materials. Few studies have been done on silver (II) fluorides as their characterization has been problematic due to their inherent air and water sensitivity. This study is the first to accurately characterize two of these materials.
