Hall effect in α-RuCl3

The Hall effect measurements performed in the layer compound α-RuCl₃ show that, in the sheets perpendicular to the c-axis, μ(300 K) ? 0.2 cm²V sec^?1; the temperature dependence of μ appears to be μ(T) = μ₀T^-n, with n = 2.3 ± 0.1, in the 180–320 K range. The transport appears to be due to electrons that move with a band type of mechanism, the main scattering process being due to the homopolar high energy phonons which modulate the thickness of the layers.
