Fig. 2: Magnetoresistance anomaly.

a Geometric diagram of the MR measurement with B in the (11-2) plane, where θ is the field angle respected to the [111] direction. MR is defined as \({{{{{\rm{MR}}}}}}=\frac{R\left(B\right)-{R}_{0}}{{R}_{0}}\times 100\%\), where \({R}_{0}\) is the zero-field resistance. b MR (top) and AC susceptibility (bottom) at 0.03 K at selected angles; inset illustrates the MR at each angle when B = 5 T. c Geometric diagram of the MR measurement with B in the (1-10) plane, which contains four high-symmetry axes. d MR (top) and AC susceptibility (bottom) at 0.03 K along the high-symmetry axes in this geometry. Vertical offsets are applied on the curves for clarity.
