Аннотация: To design films with the Fe/TiB2 nanocomposite structure, which are characterized by high saturation induction Bs, the phase and structural states and static magnetic properties of Fe-TiB2 films prepared by magnetron sputtering and subjected to subsequent annealing have been studied. According to X-ray diffraction data, either amorphous or nanocrystalline single-phase structure (an α-Fe(Ti,B) supersaturated solid solution with a bcc crystal lattice) is formed in the as-sputtered films. Depending on the film composition, the grain size of the α-Fe(Ti,B) phase varies from 45.6 to 6.5 nm; grains are characterized by high microstrain (0.21-4.96%). The annealing at 200-500 °C leads to a decrease in the lattice parameter of the α-Fe(Ti,B) phase, i.e. to its depletion of titanium and boron and to the formation of two-phase α-Fe + Fe3B structure after annealing at 500 °С. The annealing at 200-500 °C almost does not affect the grain size and microstrain of the bcc α-Fe-based phase. The amorphous state of the films is stable up to 500 °C. All studied films are ferromagnets; the saturation induction Bs (0.95-2.13 T) and coercive field Hc (0.4-5 kA/m) of the films were determined. Correlations between the Bs and Hc magnitudes and the chemical composition of the films, their phase and structural states and magnetic structure are discussed.
