a Resistivity at B = 45 T as a function of temperature. The field direction is B∥c for samples D2 and X2 and θ = 9.2∘ for X1. The inset shows an Arrhenius plot of the same data. b Resistivity of sample X1 for various field angles plotted against the c-axis component of the applied field \(B\cos \theta\). A blow-up of a region near B = 19 T is shown in the inset. Note that the spin reduction factor Rs changes sign at θ ≈ 50∘ for both α and β oscillations (see text for explanation). The c-axis resistivity for B∥c in sample X2 is also shown in the main panel.
