Abstract

The symmetry-related in-plane misorientation is investigated in an highly mismatched system of (001) Bi2Sr2CaCu2Ox(2212) thin films on (001) cubic substrates with 12 Å lattice length. Irregular in-plane orientation of 2212[510]// Sub.[120] is expected on the basis of the coincidence site lattice theory. This expectation is realized using (001)YAG (yttrium aluminium garnet) substrates. The atomic structure model is shown with regard to the interface between (001)2212 film and the (001)YAG surface.
