Abstract

The low-frequency dielectric response of hole-doped insulators La ₂Cu_1-xLi_xO₄ and La _2-xSr_xNiO₄ shows a large dielectric constant ε′ at high temperature and a steplike drop by a factor of 100 at a material-dependent low temperature T_f. T_f increases with frequency, and the dielectric response shows universal scaling in a Cole-Cole plot, suggesting that a charge-glass state is realized both in the cuprates and in the nickelates.
