Influence of Disorder on the Hall Effect in Bi${}_2$Sr${}_2$CuO${}_{6+\delta }$

Abstract

The in-plane resistivity and Hall coefficient have been measured for the single-layer compound Bi${}_2$Sr${}_2$CuO${}_{6+\delta }$ for the whole range of doping states. The deviation of the Hall coefficient, $R_H$, from a high-temperature linear behavior and the temperature dependence of the Hall angle are both only weakly dependent upon doping, contrasting with Bi${}_2$Sr${}_{2-x}$La${}_x$CuO${}_{6+\delta }$ and Bi${}_2$Sr${}_2$CaCuO${}_{8+\delta }$. This is in contradiction with former proposals that the transverse transport detects the formation of incoherent Cooper pairs in the pseudogap state. Conversely, the analysis of the data using a phenomenological angular dependent scattering rate clearly allows to distinguish between underdoped and overdoped states, and we propose that the maximum in $R_H(T)$ simply arises due to the combination of a large isotropic scattering rate and an anisotropic temperature dependent one.
