a Proton sensing setup. b Simulation results for the magnetic field distribution from the RF field in the proton sensing device (Supplementary Movie 2). c Time-dependent normalized FMR signal under different proton concentrations. A constant bias voltage of −0.7 V is applied to the device during the measurement. d Proton concentration-dependent normalized FMR signal at 100 s. Source data are provided as a Source Data file.
