Abstract

From ac magnetic susceptibility measurements on Li-doped La2 CuO4, with Hac parallel and perpendicular to the CuO plane, we find frequency-dependent behavior below a spin-glass temperature (TSG). TSG obtained from magnetic susceptibility is higher than the charge-glass temperature TCG obtained from dielectric constant measurements, indicating that spin freezes first and drives charge freezing at a lower temperature. Similar frequency dependence of the two characteristic freezing temperatures underlines that charge and spin dynamics are strongly correlated in this cuprate compound.
