BM vs TM EDMR: (a) standard BM (red) EDMR for \(\nu =250~\text {MHz}\). (b) novel TM (cyan) EDMR which avoids the strong ZFSDR signal peak. Interestingly, the half-field transitions (cyan arrows) show a phase flip of pi compared to the main resonant SDR peak transitions indicating different populations of the \(m_s=+1\) and \(m_s=-1\) state. (c) BM EDMR with \(\nu =50~\text {MHz}\). (d) TM EDMR with \(50~\text {MHz}\). The novel TM EDMR approach is also applicable to small fields (/frequencies) when the signal is usually dominated by ZFSDR. Multiple hyperfine peaks can be observed (cyan arrows) which are less suppressed than the resonant SDR peak located within the ZFSDR signal.
