Magnetoresistance (\(\:MR\left(B,\varTheta\:\right)\)) as a function of magnetic field squared (B2) at various temperatures, measured during cooldown (a) and warmup (b). In both, data sets are represented with stars and dashed lines. Solid lines, instead, are the fits to a linear dependence of \(\:MR\left(B,\varTheta\:\right)\) on \(\:{B}^{2}\) using only the higher field points.
