The influence of defects on the phase transition behavior of A2BX4-compounds was studied by diffraction methods, impedance spectroscopy and atomic force microscopy. It was found that chemical point defects have a strong effect on the transition kinetics, whereas the thermodynamic stability of different modulated phases is only slightly affected by such doping with alkali ions. The lock-in-transition from incommensurate to commensurate modulated is slowed down by several orders of magnitude. The… CONTINUE READING
