Abstract
We report a neutron and x-ray Rietveld analysis of strontium titanate down to 1.5 K. The results do not show evidence for any supplementary structural phase transition or local frozen polar ordering. These resu lts are a supplementary indication that at very low temperature stront ium titanate should display only weak local modifications of the stati c tetragonal structure with no strong signature in the diffraction pat tern.
