Correlated local distortions of the TlO layers in Tl${}_2$Ba${}_2$CuO${}_y$: An x-ray absorption study

G. G. Li, F. Bridges, J. B. Boyce +4

We have used the XAFS (x-ray-absorption fine structure) technique to investigate the local structure about the Cu, Ba, and Tl atoms in orthorhombic Tl-2201 with a superconducting t…
