| Abstract: | Precise lattice parameter measurements and intensity measurements of selected main and satellite reflections of K2CoCl4 have been performed in the temperature range 100 to 300 K in the vicinity of the low-temperature phase transition (commensurate-commensurate phase transition, T c = 142 K). A broadening of the FWHM for the h01 reflections was observed below 142 K which suggests a transition from an orthorhombic phase to a monoclinic phase. |
