摘要：

We report in-plane resistivity (rho) and transverse magnetoresistance (MR) measurements for underdoped HgBa2CuO4+delta (Hg1201). Contrary to the long-standing view that Kohler's rule is strongly violated in underdoped cuprates, we find that it is in fact satisfied in the pseudogap phase of Hg1201. The transverse MR shows a quadratic field dependence, delta rho/rho(0) = aH(2), with a(T) proportional to T-4. In combination with the observed rho proportional to T-2 dependence, this is consistent with a single Fermi-liquid quasiparticle scattering rate. We show that this behavior is typically masked in cuprates with lower structural symmetry or strong disorder effects.
