Abstract
Measurements of FIR transmission of Pb3Ge3O11 at 20. 2 cm-1 using a FIR laser are presented. Moreover, evidence for further phase transitions above Tc = 450 K are discussed.Improved lattice constants of Pb5Ge3-xSixO11 mixed crystals show a remarkable negative deviation from Vegard's rule corresponding with the respective change of Tc.Keywords
