Opis:: Conversion electron Mössbauer spectroscopy and magneto-optical Kerr effect were applied to investigate hyperfine interactions and macroscopic magnetic properties of Finemet-type thin films. Phase analysis as well as compositional evolution of hyperfine parameters and coercivity was performed in the range of chromium percentage 0 ≤ x ≤ 14. Essential differences in structure and hyperfine parameters were found for films of different chromium concentration. Coercivity shows non-monotonic dependence with minimal value at x = 5.

Opis:: The combined conversion electron (CEMS) and γ-transmission Mossbauer spectroscopy is used to investigate the differences in the bulk and surface crystallization of the amorphous Fe$\text{}_{81}$Zr$\text{}_{7}$B$\text{}_{12}$ alloy. The radio-frequency induced effects (rf collapse and side bands) are used to study the microstructure and magnetic behaviour of the alloy in the amorphous and nanocrystalline states. Rf-Mossbauer experiment permits us to distinguish soft magnetic nanocrystalline bcc-Fe phase from microcrystalline α-Fe.

Opis:: In this work, a ⁵⁷Fe conversion electron Mössbauer spectrometry and X-ray diffraction have been utilized in order to investigate the structural and magnetic order in 500 nm thick Ni-Zn ferrite films deposited on Si(100) substrate by laser ablation. Considering the contributions of the conversion electron Mössbauer subspectra corresponding to the tetrahedral (A) and octahedral (B) sites, the spinel inversion parameter in [Zn_{x}Fe_{1-x}]^{A}[Ni_{1-x}Fe_{1+x}]^{B}O₄ films has been estimated. The hyperfine field (B_{hf}) values in the investigated Ni-Zn ferrites thin films are about 5-8% smaller than those of bulk ferrites, which could be a sign of thermal magnetic relaxations due to the size effects. The distribution of hyperfine magnetic field directions was found to be affected by perpendicular anisotropy.
