Abstract
A nonuniform electron density distribution is observed in La1-x-yNdySr xCuO4 and La1-x-yEuySrxCuO4, and long-lived magnetic fluctuations in t hese compounds are studied. The dynamics of the magnetic fluctuations depends strongly on the magnetic properties of the rare-earth ions, wh ich stabilize the low-temperature tetragonal phase.
