Abstract

Behavior of ρ_ab(T) and R_H(T) is presented for LSCO and YBCO single crystals in the lightly hole-doped antiferromagnetic region, with an emphasis on the R_H(T) data. In both systems, R_H is virtually constant at moderate temperatures and tends to increase at low temperatures. Since essentially the same behavior of ρ_ab(T) and R_H(T) is observed in both LSCO and YBCO, we discuss that the in-plane charge transport properties are universal among the cuprates in the lightly-doped regime and that the R_H(T) data we obtained represent the genuine behavior of the Hall effect in this regime.
