We present a study of the in-plane and out-of-plane magnetoresistance (MR) in heavily-underdoped, antiferromagnetic YBa_{2}Cu_{3}O_{6+x}, which reveals a variety of striking features. The in-plane MR demonstrates a "d-wave"-like anisotropy…

We study angular-dependent magnetoresistance in a low $T_c$ layered cuprate Bi$_{2.15}$Sr$_{1.9}$CuO$_{6+\delta}$. The low $T_c$ ~ 4 K allows complete suppression of superconductivity by modest magnetic fields and facilitate accurate…

The anisotropy of the scattering rates, 1/$\tau_{tr} \propto T$ and 1/$\tau_H \propto T^2$, implied effectively by the anomalous temperature dependence of the normal-state in-plane Hall angle, $\cot \theta \propto T^2$, observed in the…
Using 61-T pulsed magnetic fields, the normal-state \rho_{ab} and \rho_{c} are measured in Bi-2201 system down to 0.66 K, and the coexistence of the "metallic" \rho_{ab} and the "semiconducting" \rho_{c}, usually called the charge…
We show that the resistive anisotropy of an anisotropic medium is determined by the ratio of the phase coherence lengths. In layered crystals in which the interlayer transport is incoherent, the out-of-plane phase coherence length is fixed…
