Abstract
Spin-orbit coupling in doped can result in (1) a novel electron-phonon coupling involving soft oxygen ‘‘tilting’’ phonons, and (2) stabilization of a commensurate antiferromagnetic state over a spiral state in the presence of a sufficiently large tilt distortion. This second effect may be responsible for the unusual electronic properties of .
