Domain wall probes (DW-probes) were custom-made by modifying standard commercial magnetic force microscopy (MFM) probes using focused ion beam lithography. Excess of magnetic coating from the probes was milled out, leaving a V-shaped nanostructure on one face of the probe apex. Owing to the nanostructure's shape anisotropy, such probe has four possible magnetic states depending on the direction of the magnetization along each arm of the V-shape. Two states of opposite polarity are characterised…

V-Shaped Domain Wall Probes for Calibrated Magnetic Force Microscopy

Magnetic force microscopy (MFM) qualitatively resolves stray magnetic fields, but its fundamental flaws include limited quantitative analysis and difficulties in measuring samples with heterogeneous

Magnetic force microscopy measurements in external magnetic fields—comparison between coated probes and an iron filled carbon nanotube probe

We performed magnetic force microscopy (MFM) measurements in external magnetic fields parallel to the sample plane to qualitatively study their effect on the magnetization of different kinds of MFM

Dual-tip magnetic force microscopy with suppressed influence on magnetically soft samples

This work presents a new approach to magnetic field scanning by segregating the topological and magnetic scans with two different tips located on a cut cantilever, which reduces significantly the perturbations of the magnetic tip as compared to the standard MFM method.

Nanosized corners for trapping and detecting magnetic nanoparticles

The detection down to a single nanoparticle is demonstrated, therefore the device holds the potential for the localization and detection of small numbers of molecules immobilized on the particle's functionalized surface.

Quantitative magnetic force microscopy on perpendicularly magnetized samples

We present a transfer-function approach to calculate the force on a magnetic force microscope tip and the stray field due to a perpendicularly magnetized medium having an arbitrary magnetization

Removal of electrostatic artifacts in magnetic force microscopy by controlled magnetization of the tip: application to superparamagnetic nanoparticles

This work proposes a new MFM technique, called controlled magnetization MFM (CM-MFM), based on the in situ control of the probe magnetization state, which allows the evaluation and the elimination of electrostatic contribution in MFM images.
