A Landau free energy expansion has been developed in a Þ rst attempt to describe the Pm -3m ↔ I4/mcm octahedral tilting transition in perovskite across a complete binary solid solution, CaTiO 3 -SrTiO 3 (CST). Only two parameters, the critical temperature and the coefÞ cient, λ 4 , for coupling betw
