The antiferromagnetic two-dimensional van-der-Waals material CrSBr exhibits unique electronic properties, as its conductivity is strongly dependent on the direction of the current flow with respect to its orthorhombic crystalline symmetry as well as on the anisotropic magnetic properties. In our work, we investigate the interplay of the magnetic and electronic anisotropies by magnetotransport measurements. Therefore, exfoliated CrSBr multilayers are patterned into Hall-bar structures via lift-off processes using electron-beam lithography and sputter deposition. The magnetotransport measurements are conducted in cryogenic conditions between 10 K and 200 K. By measuring the field- and angle-dependent magnetoresistance in different rotation planes of the magnetic field, we characterize the temperature- and field-dependent magnetic phase transitions of CrSBr and find an anisotropic magnetoresistance of up to 40%. We extract the anisotropy and critical magnetic fields by using free-energy simulations and demonstrate the good agreement between simulation and experimental data.
