Fig. 5: Quantum interference of chiral current.
a, False-coloured SEM image of the MZI made from the PdGa crystal. The applied electric field is along \([0\bar{1}1]\), and NLH-induced current were collected along [100]. b, Oscillations in V3ω with applied current at 30 mK in zero external magnetic field. The current was swept in both directions towards the positive and negative polarities. c, Oscillations in V3ω with applied magnetic field μ0H at 30 mK with a current of 20 μA. d, Dependence of the oscillations in V3ω on the sweep direction of μ0H at 30 mK with a current of 20 μA. The magnitude of the field-sweep rate in c and d was 0.83 mT s−1. The magnetic field was applied out of plane along the y-axis. Here V3ω is the in-phase component of the lock-in signal. Scale bar, 10 μm (a).
