Burst eddy current testing with diamond magnetometry [PDF]
Applied Physics Letters, 2022 In this work, a burst eddy current testing technique based on the employment of a diamond nitrogen vacancy (NV) center magnetometer with the Hahn echo (HE) sequence is demonstrated. With the confocal experiment apparatus, the HE-based NV magnetometer attains a magnetic sensitivity of 4.3 nT/Hz and a volume-normalized sensitivity of 3.6 pT/Hz mm−3 ...
