PTBcsm_7-Nanometerskala — Test sample with magnetic structures used for the measurements performed within the scope of the interlaboratory comparison. The light green areas consist of a magnetic layer; in the darker areas, this layer was removed by means of lithography.

So far, no internationally standardized measurement procedures have been available to measure magnetic field distributions that vary spatially on the nanometer scale. The NanoMag EMPIR metrology research project, which was spearheaded by PTB and has recently been completed with success, bridges this gap and will allow internationally comparable measurements of magnetic field distributions with high spatial resolution.
