K. Levin et al., SPIN DYNAMICS AND IMPLICATIONS FOR SUPERCONDUCTIVITY - SOME PROBLEMS WITH THE D-WAVE SCENARIO, Journal of superconductivity, 7(3), 1994, pp. 563-570
We review the spin dynamics of the normal state of the cuprates with s
pecial emphasis on neutron data in both the YBa2Cu3O7-delta and La2-xS
rCuO4 systems. When realistic models of the Fermi surface shapes are i
ncorporated, along with a moderate degree of spin fluctuations, we fin
d good semiquantitative agreement with experiment for both cuprates. B
uilding on the success of this Fermi-liquid-based scheme, we explore t
he implications for d-wave pairing from a number of vantage points. We
conclude that our present experimental and theoretical understanding
is inadequate to confirm or refute the d-wave scenario.
