Fig. 4. MR as a function of applied field at various angles in ZrSiS.
(A) MR versus μ0H at various angles (full data in the Supplementary Materials) along with fits to MR = 1 + c1H + c2H2, where c1 and c2 are the relative weights given to the linear and quadratic terms of the equation. Solid, smooth lines are the fits, whereas oscillating lines are the data. (B) Extracted c1 and c2 dependencies from the full 9-T MR versus H curves taken at 0°, 10°, 20°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 70°, 80°, 85°, 87.5°, 90°, 92.5°, 95°, 100°, and 105°, where θ is taken as the angle between the applied field and the current, which is applied along the a axis. Solid squares and solid triangles are the extracted values for c1 and c2, respectively.
