Fig. 2: Characterization of spin-bath-induced dephasing using DEER measurements.
From: Unraveling quantum dephasing of nitrogen-vacancy center ensembles in diamond
a Measured DEER spectrum at a 9.5 Gauss magnetic field. The peaks marked by triangles are related to the dark spin transitions which do not belong to P1 center, while other peaks are P1 center related. The peak marked by a star is used in measurement in (b) and (c). b Pulse-sweep DEER sequence and the corresponding measured signals with the example sample. c Duration-sweep DEER sequence and the corresponding measured signals from the same sample.
