Abstract
Through the example of the Pm 3 m – I4 / mmm structural phase transition in LaAg1-x Inx (x∼0.2), a general procedure is given in this paper to model and predict the domain pair and domain wall formation using a group theoretical approach and a Landau-Ginzburg type continuum theory. The heterogeneous order parameter profile can then be calculated by using an initial value scan method based on the equilibrium conditions of the order parameter and the minimization of the total elastic energy. The dependence of the domain wall profile on different expansion coefficients of the free energy is demonstrated numerically in several examples.
