Field and angular dependence of resistivity. a Temperature dependence of the magnetoresistance at various temperatures (T = 2, 3, 6, 7, 8, 9, 13, 20, and 30 K) with the current parallel to ac-plane and the external magnetic field H is parallel to b-axis; it is maximized at 2 K and 9 T with MR = 1.66 × 106%. b Angular dependence of the magnetoresistance at 2 K with the current within the ac-plane, and the field rotates from the b-axis to the ac-plane. The inset shows that the MR tends to saturate under high magnetic field when the direction of the field is close to the ac-plane. c Scaling behavior of the field dependence of the MR at various magnetic field directions. Upper inset: MR shows a power law behavior as MR ∝ H 1.787 at 2 K, lower inset: scaling factor εθ as a function of θ. d The MR of α-Ga up to 60 T at 4.2 K, with the current within the ac-plane and H parallel to the b-axis
