Abstract: In a method for scanning microscopy, for which the surface of a sample is scanned point-by-point using a tunnel tip and locally resolved tunnel current measurement is performed, during scanning the tunnel tip is remagnetized by a predetermined remagnetization frequency, and from the tunnel current (It) or a z coordinate of the distance between the tunnel tip and the sample or a value derived from this, locally resolved signal components are derived, occurring at the remagnetization frequency and being characteristic for magnetic sample properties, whereby on the basis of the derived signal components an imaging of the magnetic structure of the sample surface is performed.
