Electrical Relaxation in Rare Earth Doped Cubic Lead Fluoride.

reportActive / Technical Report | Accession Number: ADA125066 | Open PDF

Abstract:

Audio frequency complex impedance measurements are performed over the temperature range 5.5-380K on lead fluoride doped with ten rare earths and lanthanum at various concentrations. It is found that the complexity of the relaxation spectrum increases as the size of the trivalent ion decreases. Specifically, for the largest rare earths, only one relaxation is found.
