Abstract
Glasses of composition $Bi_2Sr_2CaCu_nO_{6+n} (n = 2 \hspace{2}to\hspace{2} S)$ have been prepared hy the melt quenching technique. Thermal, electrical, and magnetic properties of tlicsc glasses linvc 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 $Bi_2O_3$ and CuO as glass formers. It is shown that the properties of the glasses investigated in this work are consistent with the model.
