Effect of twin boundaries on scattering processes of normal and fluctuating carriers in YBa₂Cu₃O₇₋δ single crystals
Effect of twin boundaries on the normal and fluctuating conductivity of YBaCuO single crystals has been studied. The temperature dependence of the excess conductivity has been shown to be described satisfactorily by the Lawrence-Doniach theoretical model. The twin boundaries are efficient scattering...

| description |
Effect of twin boundaries on the normal and fluctuating conductivity of YBaCuO single crystals has been studied. The temperature dependence of the excess conductivity has been shown to be described satisfactorily by the Lawrence-Doniach theoretical model. The twin boundaries are efficient scattering centers of normal and fluctuating carriers. The determined values of coherence length perpendicular to the ab plane εc(0) agree satisfactorily with those obtained from magnetic measurements for stoichiometric YBaCuO crystals. |
