Abstract
Glasses of composition Bi2Sr2CaCunO6+n (n = 2 to 5) have been prepared by the melt quenching technique. Thermal, electrical, and magnetic properties of these glasses have been examined. Electrical conductivities suggest the validity of the multiphonon assisted hopping model. Susceptibilities indicate weak antiferromagnetic coupling. However, the electron spin resonance (ESR) studies suggest a large proportion of spins to be ESR inactive. A structural model of the glasses has been proposed that considers both Bi2O3 and CuO as glass formers. It is shown that the properties of the glasses investigated in this work are consistent with the model.
