Description
Ferromagnetic nanoparticles can be used as building blocks for advanced thin film magnets, and can also be used in data storage and biomedical technologies. Nano-crystalline ferrites with the chemical formula NixZn (1 - x) Fe2O4, where x = 0, 0.2, 0.4, 0.6, 0.8, 1.0 show anti-corrosion properties and suppress electromagnetic interference, in the case of their use as pigments in protective coatings. Atomic force microscopy makes it possible to monitor their dispersion in the coating thanks to the use of a dedicated measurement mode [1]. In the AC MFM two-pass technique, the second pass vibration of the probe lever is used to measure the magnetic force gradient (similar to other non-contact modes). The images in the collection show the use of magnetic force microscopy to visualize samples of protective coatings containing pigments in the form of ferromagnetic nanoparticles. Thanks to the use of the aforementioned technique and the probe with a cobalt coating, it became possible to clearly determine their location on the basis of differences in amplitude and phase of magnetic interactions. The collection contains 8 images.
