This part of IEC62607 establishes a standardized method to characterize spatially varying magnetic fields
with a spatial resolution down to 10nm for flat magnetic specimens by magnetic force microscopy (MFM). MFM primarily detects the stray field component perpendicular to the sample surface.
The resolution is achieved by the calibration of the MFM tip using magnetically nanostructured reference materials.
The objective of this document is to define and describe:
reference materials for traceable high resolution magnetic strayfield measurements;
the calibration procedures to determine the instrument calibration function (ICF) and, if required, MFM key parameters entering the deconvolution process;
the deconvolution process which allows to calculate quantitative stray field data
from the measured MFM data using the ICF;
the evaluation of the measurement uncertainty, including the prevention of potential
artefacts which can occur during the measurement leading to a misinterpretation of
the results.
