Fig. 2: Quantum oscillations in the insulating and field-induced metallic states of YbB12.
From: The reverse quantum limit and its implications for unconventional quantum oscillations in YbB12
a Magnetoresistance and b contactless resistance showing quantum oscillations in the insulating state and metallic state, respectively. Insets show a derivative of magnetoresistance and b background subtracted contactless resistance as functions of inverse field. c Insulating state quantum oscillations have a field-independent frequency of 740 ± 60 T and metallic state quantum oscillations have a field-dependent frequency (H ∥ [100]). Lines are guides for the eye. d Angular dependence of the insulator–metal transition field (HIM). Angles correspond to rotations in the [100]−[011] plane referenced to [100]. All measurements were at ≈650 mK.
