(a) Temperature-dependent LMR data for sample a1. (b) Magnetoresistance data as a function of the angle between the and
fields. The green curves of a,b are the fits to the LMR data in the semiclassical regime. The y axes are the change of the resistivity with respect to the zero-field resistivity, Δρ=ρ(B)−ρ(B=0). (c–e) The magnetoresistance as a function of the angle for samples c2, a3 and c4 at a fixed field.
