Local structure of Sr₂CuO3.3, a 95 K cuprate superconductor without CuO₂ planes

The local structure of the highly “overdoped” 95 K superconductor Sr₂CuO3.3 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 c axis; 2) at these levels of precision the Cu sublattice is tetragon...
