摘要：

The type of magnetocrystalline anisotropy (MCA) of Sm-Fe-Co-Ti alloys and their hydrides with a ThMn12-type structure has been established by magnetometry at room temperature. Using atomic force microscopy (AFM) in combination with magnetic force microscopy (MFM), the state of their surface was studied. The initial SmFe11Ti and SmFe5Co6Ti samples were obtained by argon arc melting. The SmFe11Ti alloy was subjected to a hydrogenation procedure, as a result of which the SmFe11TiH0.4 and SmFe11TiH1 samples were synthesized. Using AFM and MFM, the features of topography, defects of the investigated surfaces, domain structure, morphology of magnetic inclusions of the initial samples and their hydrides were established. The main magnetic characteristics of the Sm-Fe-Co-Ti-H systemobtained using magnetometry have been compared with the results of MFM studies.
