摘要：
A nonuniform electron density distribution is observed in La1-x-yNdySrxCuO4 and La1-x-yEuySrxCuO4, and long-lived magnetic fluctuations in these compounds are studied. The dynamics of the magnetic fluctuations depends strongly on the magnetic properties of the rare-earth ions, which stabilize the low-temperature tetragonal phase.
