The local structure of the highly "overdoped" 95 K superconductor Sr<sub>2</sub>CuO<sub>3.3</sub> determined by Cu K X-ray absorption fine structure (XAFS) at 62 K in magnetically oriented samples shows that 1) the magnetization is perpendicular to the <i>c</i> axis; 2) at these levels of precision the Cu sublattice is tetragonal in agreement with the crystal structure; the O sublattice has 3) continuous -Cu-O- chains that orient perpendicular to an applied magnetic field; 4) approximately half- ...[more]
