The seminar will begin with an introduction to the case study of rare-earth phosphate glasses, their optical and magnetic materials-interest, and an overview of the structural work that determines their basic structural units. The inaccessibility of conventional diffraction and spectroscopy methods towards the minimum rare-earth distance, which dictates their physical properties, is explained. There follows a presentation of the development of several novel and complex diffraction methods that help reveal this materials-centred important R…R separation: via anomalous X-ray and neutron scattering, and a magnetic difference experiment.

This talk is part of the Surfaces, Microstructure and Fracture Group series.
