Superconductivity suppression at twin boundaries and longitudinal and transversal transport anisotropy in oxygen deficient YBa₂Cu₃O₇₋ₓ single crystals

Superconductivity suppression at twin boundaries and longitudinal and transversal transport anisotropy in oxygen deficient YBa₂Cu₃O₇₋ₓ single crystals

The temperature dependences of the conductivity along and across the basis plane have been measured in YBa₂Cu₃O₇₋ₓ single crystals with different oxygen non-stoichiometry. In the oxygen-deficit samples, an inhomogeneous oxygen distribution within the crystal bulk is found, that results in the format...
