In-Plane Magnetoresistance Obeys Kohler’s Rule in the Pseudogap Phase of Cuprate Superconductors

We report in-plane resistivity (ρ ) and transverse magnetoresistance (MR) measurements for underdoped HgBa 2 CuO 4+δ (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, δρ/ρ 0 =aH 2 , with a(T)∝T −4 . In combination with the observed ρ∝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
