Numerical Characterization of Magnetic Vortex Probe Imaging for Magnetic Force Microscopy

We study theoretically the performance and limitations of the magnetic vortex probe for magnetic force microscopy (MFM). In the ideal case, the only magnetically active part of the probe is the magnetic vortex core (VC) existing in the center of a Permalloy (Py) disk located at the apex of a non-mag...
