Characterization of the 105K Phase Transition in Flux-Grown SrTi0₃

Abstract

An electron-paramagnetic-resonance study of the 105 K phase transition in a flux-grown low dislocation density SrTi03 crystal is described. The rotational order parameter (p reveals no time dependent effects, and the transition is within experimental accuracy continuous. These results agree with recent X-ray and neutron-scattering measurements of the lattice parameter, a = a(Tc) x cosφ being continuous at Tc. © 1983, Taylor & Francis Group, LLC. All rights reserved.
