Phenomenological model for magnetotransport in a multi-orbital system
Canio Noce, Mario Cuoco
Abstract
By means of the Boltzmann equation, we have calculated some magnetotransport quantities for the layered multi-orbital compound Sr2RuO4. The Hall coefficient, the magnetoresistance and the in-plane resistivity have been determined taking into account the Fermi surface curvature and different time collisions for the electrons in the t2g bands. A consistent explanation of the experimental results has been obtained assuming different relaxation rates for the in-plane transport with and without an applied magnetic field, respectively.
