Co. Rodriguez et al., ELECTRONIC SUSCEPTIBILITY OF YBA2CU3O7 AND ITS RELATION TO PHONON ANOMALIES, Journal of physics. Condensed matter, 5, 1993, pp. 377-380
A first-principles prediction of the q dependence of the electronic su
sceptibility of YBa2Cu3O7 and the relation to experimentally observed
phonon anomalies is presented.
