Temperature Dependence of Resistivity and its Anisotropy of Ba-Y-Cu-O Single Crystals

Abstract

The temperature dependence of resistance of single crystals of Ba 2 YCu 3 O 7- y was examined. The resistance perpendicular to the plane exhibited a semiconductor-like temperature dependence, while the resistance parallel to the a - b plane was metallic. Thus, the anisotropy of conductivity increased at low temperature.
