Abstract

High-angle double-crystal X-ray diffractometry (HADOX) has been applied to measure the intensity around the three reciprocal lattice points of KMnF₃: namely, 600, 060 and 006. Each point splits into two in the tetragonal phase according to the appearance of three kinds of domains; the temperature dependence of the intensity of component peaks at these points was measured under identical conditions. The results show that the domain population is nearly constant in contrast to the case of SrTiO₃ where the population varies with temperature. The data are also analysed in the temperature range of the two-phase coexistence.
