Abstract

It has been suggested that defects cause the central peak in SrTiO3. This paper presents a mean-field study of point defects which couple so strongly to the order parameter that nonlinear interactions in neighboring cells are important. Fair agreement with experimental results from electron paramagnetic resonance is found with a concentration of defects fitted to inelastic neutron scattering results. The hindered reorientation of domains is found to be consistent with this concentration of defects.
