Abstract:	A nonuniform electron density distribution is observed in La_{1−x− y}Nd_ySr_xCuO₄ and La_1−x−yEu_ySr_xCuO₄, 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. Pis’ma Zh. éksp. Teor.
