Structure of (CuO) 2 double layers in superconducting YBa2Cu3O7

The nature of planar defects in superconducting YBa2Cu3O7 is clarified using detailed local structure determination employing high-resolution electron microscopy and computer-assisted image analysis. The results reveal the identity of a (CuO)2 double layer intercalation. Within this double layer, th...

Description
Summary:The nature of planar defects in superconducting YBa2Cu3O7 is clarified using detailed local structure determination employing high-resolution electron microscopy and computer-assisted image analysis. The results reveal the identity of a (CuO)2 double layer intercalation. Within this double layer, the Cu atoms remain in planar fourfold coordination with O, identical to their arrangement in the single CuO layers of the YBa2Cu3O7 matrix. (C.D.)
