We have reported the electrical conductivity and the conductivity relaxation in fluoride glasses in the system 40ZrF4-20BaF2-10YF3-(30-x)LiF-xNaF; 0≤x≤30. We have observed a mixed mobile ion effect in these mixed alkali fluoride glasses. Using modulus formalism we have shown that the conductivity relaxation also exhibits the mixed mobile ion effect as does the dc conductivity. We have observed that the relaxation mechanism is independent of temperature but dependent on the composition.
