Interplay of Disorder and Spin Fluctuations in the Resistivity near a Quantum Critical Point
Interplay of Disorder and Spin Fluctuations in the Resistivity near a Quantum Critical Point
The resistivity in metals near an antiferromagnetic quantum critical point (QCP) is strongly affected by small amounts of disorder. In a quasiclassical treatment, we show that an interplay of strongly anisotropic scattering due to spin fluctuations and isotropic impurity scattering leads to a large regime where the resistivity varies as …
