Influence of defects on the critical behaviour at the \boldmath{105} K structural phase transition of SrTiO $_{3}$ : I. The broad component

H. Hünnefeld, T. Niemöller, J. R. Schneider +2

The critical fluctuations in SrTiO $_{3}$ near its $105 K$ structural phase transition were studied with triple axis diffractometry using high energy ( $\geq 100 k e V$ ) synchrotron radia…

Oxygen Ordering Superstructures and Structural Phase Diagram of YBa_2Cu_3O_{6+x} Studied by Hard X-ray Diffraction

M. v. Zimmermann, T. Frello, N. H. Andersen +10

High energy x-ray diffraction is used to investigate the bulk oxygen ordering properties of YBa_2Cu_3O_{6+x}. Superstructures of Cu-O chains aligned along the b axis and ordered wi…
