Ionic conductivity, N.M.R. and neutron diffraction of the fluorite Rb1-x Bi x F1+2x and of the ordered phase rbbi3F10

Abstract The aim of the present study is to establish correlations between the electrical and structural properties in Rb1-X Bi X F1+2X and RbBi3F10. Nuclear magnetic resonance and neutron diffraction have proved to be helpful techniques. They have allowed us to obtain consistent results which account for the evolution of ionic conductivity properties with amount of substitution.
