Abstract
We conclude from the analysis of the experimental NMR data for electron-doped cuprates that the Coulomb effects caused by doping lead to dynamical spatial phase separation that contributes to the nuclear spin relaxation. Remarkable, the 'infinite-layer' Sr0.9La0.1CuO2 reveals unexpected electron-hole symmetry. Its 63Cu nuclear spin relaxation rate is the sum of a constant and the temperature dependent dissipation components, moreover, the latter turns out to be identical to the 1/63T1(T)-behavior in the stoichiometric hole-type compound YBa2Cu4O8. Connection to fluctuations of a magnetic sub-phase is discussed.
