Abstract

Measurements of the complex dielectric permittivity in (Li ₂O)_x(B₂O₃)_100-x, and halide-doped (Li₂O)_x (LiCl)_y(B ₂O₃)_100-x-y glasses conducted in the nearly constant loss (NCL) regime at low temperatures are reported. Scaling properties reveal that the NCL in (Li₂O)_x(B₂O ₃)_100-x is largely ionic in origin for these materials and increases in proportion to the Li₂O content. However, at low Li ₂O content, the NCL becomes dominated by a non-ionic loss arising from the borate network or other impurity polarizations. Halide doping is seen to produce an additional enhancement of the NCL that is consistent with its known enhancement of the bulk conduction.
