Electric field dependence of the dielectric susceptibility in K_1-xLi_xTaO₃

Results are presented for the dielectric function ε* = ε1 + iε2 in K1-xLixTaO3 in the frequency range 10 < f < 106 Hz and for several fields. The data are analysed in terms of dielectric relaxation, and it is shown that the electric bias field modifies the relaxation behaviour drastically. © 1984.
