(a) dHvA measurements of CeRhIn₅ at high fields parallel to the a-axis performed using a piezo-cantilever in a hybrid magnet up to 45 T. The main panel shows the field dependence of the dHvA amplitude of one of the new frequencies above B*. The inset at the top shows the oscillations after subtracting the background while the 1/B dependence is shown in the lower inset. (b) The Fourier transforms of the dHvA data for a field window below (10 T <B < 30 T) and above (45 T< B< 70 T) B*. Both reproduced from from Jiao et al., Ref. [48].
