TM EDMR with different (de-)modulation frequencies: (a) FFT illustration of the standard TM EDMR of this paper. (b) TM EDMR spectra with higher (cyan) and lower (blue) demodulation frequency. The two spectra are plotted over each other to highlight the similarities of both sidebands. (c) and (d) TM EDMR with high BM and low AM. (e) and (f) with high BM and high AM leading to a low sideband (blue) and a very high sideband (cyan). Especially this approach is attractive since it can bring the demodulation frequency far above the operation regime of magnetic field coils towards the shot-noise limit.
