DESCRIPTION:The seminar will begin with an introduction to the case study 
 of rare-earth phosphate glasses\, their optical and magnetic materials-int
 erest\, and an overview of the structural work that determines their basic
  structural units. The inaccessibility of conventional diffraction and spe
 ctroscopy 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 hel
 p reveal this materials-centred important R...R separation: via anomalous 
 X-ray and neutron scattering\, and a magnetic difference experiment.
