Abstract

We provide a review of angular dependent magnetoresistance oscillations (AMRO) for measuring the Fermi Surface (FS) of two-dimensional (2d) materials. Using four-terminal, inter-planar, electrical transport in low temperatures and high magnetic fields, the magneto resistance (MR) is observed with changing polar and azimuthal angles. As an example, analysis, we use a reported sample set of data from the organic conductor κ-(BETS)₂FeBr₄ [1] taken at T = 0.6K and B = 27T, for which we calculate a Fermi momentum k_F = 0.182 Å.
