- 論文の詳細を見る
The dynamical spin susceptibility, X(q, ω), of the extended t-J model, which reproduces Fermi surfaces of LSCO and YBCO type of high-T_c cuprates, has been evaluated in the slave-boson mean field approximation based on the uniform (u-) and the d-wave singlet (s-) RVB states. The calculated results show reasonable agreement with neutron scattering data for the incommensurate structure in LSCO. For the commensurate structure in 90 K YBCO, the ω-dependence shows general agreement, but the location of the strongest peak at low temperatures does not. The temperature (T) dependences of the rates, T^<-1>_1 and T^<-1>_G , and the shift of NMR are consistent with experimental data in the high-doping region, while they are not in the low-doping (but superconducting) region. We propose that the sharp drop in (T_1T)^<-1> above T_c in the low-doping region may be due to singlet formation.
