Abstract
Linearly polarized synchrotron radiation is used to study the structure of magnetically aligned layered copper oxide high temperature superconductors. Polarized extended X-ray absorption fine structure (EXAFS) measurements of oriented powders of YBa2Cu3O6.9 are reported at temperatures ranging from 20-300 K. Measurements made at the Cu K-edge with the X-ray polarization vector oriented perpendicular and parallel to the c axis can be used to effectively probe the structure around the Cu-atoms in the ab (horizontal layer) plane as well as in the c (vertical layer) plane.
