title = "Positional disorder of Ba in the thermoelectric germanium clathrate Ba6Ge25",
abstract = "The study of local structure of Ba6Ge25 was done at 40 K and room temperature. The X-ray diffraction and the atomic pair distribution function technique were used for the study. It was found that two out of three types of Ba atoms in Ba6Ge25 move off their positions and become locked in split sites at low temperatures.",
