Abstract
The mechanism of spin-phonon coupling (SPC) and possible consequencies for the properties of high- copper oxides are presented. The results are based on ab-initio LMTO band calculations and a nearly free-electron (NFE) model of the band near . Many observed properties are compatible with SPC, as for the relation between doping and for spin excitations and their energy dependence. The main pseudogap is caused by SPC and waves along [1,0,0], but it is suggested that secondary waves, generated along [1,1,0], contribute to a 'waterfall' structure. Conditions for optimal , and the possiblities for spin enhancement at the surface are discussed.
