摘要：
The use of the t-J model of Cu-O planes and projection operator technique for the Hubbard operators allows us to take proper account of strong electron correlations inherent in cuprate high-T, superconductors. A number of unusual properties of cuprates can be reproduced in this approach. Among them are the peculiarities of the temperature and concentration dependencies of the spin-lattice relaxation and spin-echo decay rates, the resonance peak and the incommensurate low-frequency magnetic response in neutron scattering.
