Symmetry-mode analysis of the phase transitions in SrLaZnRuO₆ and SrLaMgRuO₆ ordered double perovskites

Structural investigations under temperature variation were carried out on SrLaMRuO₆ (M = Zn and Mg) double perovskites using diffraction techniques and a symmetry-mode analysis approach. The temperature versus tolerance factor phase diagram was completed for SrLnMRuO₆.
