Abstract

Planar defects in the 2-2-3 type of new superconducting oxide, R2B2Cu3Oz[R is (Eu1-xCex), (Ba1-yEuy); x and y are about 0.33 and z is about 8.54], recently discovered by Sawa et al. (to be published in J. Phys. Soc. Jpn.) are examined by high-resolution transmission electron microscopy. The planar defects are derived by the local replacements of R2O2-layers by R-layers to form defect stabs of 1.2 nm thickness, having local structure similar to that of RBa2Cu3Oy.
