Charge Transport Properties of Lightly-Doped Cuprates: Behavior of the Hall Coefficient
نویسندگان
چکیده
Behavior of ρab(T ) and RH(T ) is presented for LSCO and YBCO single crystals in the lightly hole-doped antiferromagnetic region, with an emphasis on the RH(T ) data. In both systems, RH is virtually constant at moderate temperatures and tends to increase at low temperatures. Since essentially the same behavior of ρab(T ) and RH(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 RH(T ) data we obtained represent the genuine behavior of the Hall effect in this regime.

Stripes and Charge Transport Properties of High-tc Cuprates
Unusual features in the in-plane charge transport in lightly hole-doped La2−xSrxCuO4 single crystals are described. Notably, both the in-plane resistivity and the Hall coefficient show a metallic behavior at moderate temperatures even in the long-range-ordered antiferromagnetic phase, which obviously violates the Mott-Ioffe-Regel criterion for the metallic transport and can hardly be understood...

متن کاملThermal conductivity of Pr1.3-xLa0.7CexCuO4 single crystals and signatures of stripes in an electron-doped cuprate.
It was recently demonstrated that the anisotropic phonon heat transport behavior is a good probe of the stripe formation in La(2-x)Sr(x)CuO(4) (LSCO) [Phys. Rev. B 67, 104503 (2003)]]. Using this probe, we examined an electron-doped cuprate Pr(1.3-x)La(0.7)Ce(x)CuO(4) (PLCCO) and found that essentially the same features as those in LSCO are observed. Moreover, the in-plane resistivity rho(ab) o...
متن کاملCombination rules, charge symmetry, and Hall effect in cuprates.
The rule relating the observed Hall coefficient to the spin and charge responses of the uniform doped Mott insulator is derived. It is essential to include the contribution of holon and spinon three-current correlations to the effective action of the gauge field. In the vicinity of the Mott insulating point the Hall coefficient is holon dominated and weakly temperature dependent. In the vicinit...
