Observation of oxygen-vacancy-ordered domains in oxygen-deficient single-crystal YBa2Cu3O/sub 6.7/
- 1. ATandT Bell Laboratories, Murray Hill, New Jersey 07974
Description
Ordered domains due to oxygen vacancies in oxygen-deficient YBa2Cu3O/sub 6.7/ single crystals have been imaged by dark-field electron microscopy using the diffuse diffraction spots centered at ((1/2, 0,0). When projected along the c axis, the ordered domains have longitudinal and transverse dimensions of ∼200 and ∼20 A, respectively. The longitudinal direction of the domains is parallel to the Cu-O chain direction (i.e., b axis). The vacancy-ordered domains are estimated to occupy approx. <3% of the sample volume
