Magnetic field dependence of time-resolved traces. Contour plots of TRKR signal as function of applied magnetic field B x and delay time, using pump excitation powers of 0.3 mW (a) and 10 mW (b). Note the different intensity scales in the two panels. White lines are the calculated magnetic field dependencies of the electron Larmor frequency without nuclear contribution. c Waterfall of the TRKR spectra in the magnetic field range of 22–30 mT (black lines). Red dashed lines, plotted over the black lines, are the fits by AKR. d Extracted fit functions from c are shown with phase φ set to zero to highlight the stability of the frequencies around a whole integer of TR
