The SNDM setup.
The SEM image of a CNT probe tip.
(a) The signal image of the domain wall SLT obtained by the SNDM with the CNT probe. (b) The and (c) signal intensity distributions in the domain boundary of SLT. The solid line shows the CNT probe results, while the dashed line corresponds to the Pt-coated probe.
(a) The fifth scanned signal SNDM image of the multidomain SLT obtained using the CNT probe. (b) The signal intensity distribution on the domain boundary of SLT, after 12 scan repetitions.
(Color online) Histograms of the domain wall width distribution for both (a) before and (b) after the long-term durability tests. and are, respectively, the average values of for the CNT and Pt-coated probes, shown with their respective standard deviations.
