Related item:: Modelling the angle-dependent magnetoresistance oscillations of Fermi surfaces with hexagonal symmetry
Description:: By solving the Boltzmann transport equation we investigate theoretically the general form of oscillations in the resistivity caused by varying the direction of an applied magnetic ﬁeld for the case of quasi-two dimensional systems on hexagonal lattices. The presence of the angular magnetoresistance oscillations can be used to map out the topology of the Fermi surface and we study how this effect varies as a function of the degree of inter- plane warping as well as a function of the degree of isotropic scattering. We ﬁnd that the angular dependent effect due to in-plane rotation follows the symmetry imposed by the lattice whereas for inter-plane rotation the degree of warping dictates the dominant features observed in simulations. Our calculations make predictions for speciﬁc angle-dependent magnetotransport signatures in magnetic ﬁelds expected for quasi-two dimensional hexagonal compounds similar to PdCoO 2 and PtCoO 2 .
