Figure 5: Transient breakdowns in the optically detected EPR signal.
From: Local dynamics of topological magnetic defects in the itinerant helimagnet FeGe
(a) EPR signal of an NV centre showing a splitting below TN. The transient breakdowns in the EPR signal below TN indicate a sudden change of the local magnetization probed by the NV center (white arrows). (b,c) Temperature evolution and corresponding EPR signal. Transient breakdowns in the EPR signal are detected as long as the temperature changes and vanish completely after the temperature is stabilized.
