Changes in the polaron-like local distortions are strongly correlated with the magnetization in the CMR manganites, for bulk powders, thin films and co-doped material. In addition the e g bands are temperature dependent near T c - but only for CMR materials. These results emphasize the subtle balance of interactions in these systems.
