Magnetic Domain Imaging Using Magnetic Force Microscopy

This work deals with problem about study of magnetic domains by magnetic force microscopy. We introduce scanning probe microscopy with a focus on technical details such as calibrations and scanner defects. The calibrations were checked on two different microscopes Bruker Dimension Edge and attoAFM/MFM Ixs. The microscopes where then used for magnetic domains studies. On first microscope at room temperature was measured thin film of garnet (YSm)3(FeGa)5O12 and it was compared with Kerr microscopy. On second one (atto AFM/MFM Ixs) we dealt with evolution of domains in uniaxial ferromagnet UCoGa at low temperatures (under and around Curie temperature Tc = 48 K) including dependency on magnetic fields. There were measured several dependences of single crystal UCoGa for different (low) temperatures and different magnetic fields
