Fig. 3: Angle-dependent dHvA oscillation and in-plane MR of BaGa2.

a Angle-dependent dHvA oscillations at 1.8 K. b Corresponding FFT spectra with θ varying from 0° to 90°. c FFT frequencies as a function of angle. Solid red line is the fitting curve with equation F = F0/cos θ. Error bars are estimated from sample holders and defined as s.d. d Polar plot of MR at 9 T (violet dots) and 14 T (red dots) with B always vertical to I at 2.5 K.
