Variable Field Magnetic Force Microscopy
 Turčan, Igor ; Nováček, Zdeněk (referee) ; Urbánek, Michal (advisor)
The bachelor's thesis deals with magnetic force microscopy of permalloy discs in an external magnetic field. Main objectives of the thesis are design of an external magnetic field module, preparation of magnetic probes, fabrication of samples and the measurement itself. We prepared functional probes with various magnetic coatings. For the measurement in external magnetic field we fabricated probes with a~layer of magnetically hard Co and for the measurement without external magnetic field we used probes with a~layer of magnetically soft permalloy. Our probes are at least comparable with standard commercial probes. We observed the cores of magnetic vortices, using our home-coated probes with no external magnetic field and also in the external magnetic field. Further, we study the influence of the external magnetic field on nucleation of the cores of magnetic vortices. Experimental techniques used for fabrication and measurement of the samples are briefly summarized.
