20SIP04qMOIF Round Robin Comparison results

To provide worked examples of quantitative Magneto-Optical Indicator Film measurements in the frame of the EMPIR project 20SIP04qMOIF, Innovent, PTB and TÜBİTAK performed a Round Robin Comparison by measuring the stray field distributions of magnetic scales using the MOIF systems set up in 15SIB06 NanoMag. TÜBİTAK used its high-resolution confocal microscope. Innovent and PTB used calibrated MagView systems. The measured field distributions are compared. As a secondary parameter, the pole width of the written pole pattern was analyzed and compared.
