Analysis of domain structure parameters of RFe11Ti (R = Y, Gd, Ho, Er) single crystals based on magnetic force microscopy data
The results of an experimental study of the magnetic domain structure on the basal plane of RFe11Ti single crystals (R=Y, Gd, Ho, Er) by magnetic force microscopy are presented. At room temperature, the compounds are characterized by magnetocrystalline anisotropy of the «easy axis» type. Based on th...

| description | The results of an experimental study of the magnetic domain structure on the basal plane of RFe11Ti single crystals (R=Y, Gd, Ho, Er) by magnetic force microscopy are presented. At room temperature, the compounds are characterized by magnetocrystalline anisotropy of the «easy axis» type. Based on the magnetic force microscopy data, the sizes of domains on the basal plane of the samples were determined. Using the Bodenberger-Hubert method, the surface energy density of domain walls γ was determined for all compounds based on the magnetic force microscopy data: YFe11Ti – 4,05 mJ/m2, GdFe11Ti – 5,93 mJ/m2, HoFe11Ti – 4,97 mJ/m2, ErFe11Ti – 2,98 mJ/m2. The cube counting method was used to calculate the fractal dimension DL of the stray fields of the domain structure at different heights from the surface (0,1 – 9 μm). DL on the surface of the z(0) sections has values of 2,62 for compounds with R = Y, Gd, Ho and 2,72 for R=Er. For all samples, DL has a maximum near the surface. |
