Abstract
The effect of dilution by the non magnetic atoms Ga and Zn, on the spin freezing temperature of the insulating spin-glass, amorphous compound Pb 2MnFeF9 has been studied by ac susceptibility and 19 F N.M.R. techniques. Information was also obtained on the local structure of these glasses. The results are consistent with a model of a glassy network of chains of corner sharing MF6 octahedra (M = Fe, Mn), with Pb 2+ in interstitial sitesKeywords
