Intrinsic Hall response of the CuO2 planes in a chain-plane-composite system of YBa2Cu3Oy

Abstract

The Hall coefficient is measured in YBa${}_2$Cu${}_3$O${}_y$ untwinned single crystals for a wide range of doping. We show that the Hall conductivity and the Hall angle of the {\it CuO${}_2$ planes} in YBa${}_2$Cu${}_3$O${}_y$ can be extracted from measurable transport properties regardless of the conduction of the Cu-O chains nor the in-plane anisotropy of the CuO${}_2$ planes. The present analysis allows us to discuss the genuine Hall effect in the CuO${}_2$ planes alone in YBa${}_2$Cu${}_3$O${}_y$ without any complications due to the Cu-O chains.
