| 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 Fe81Zr7B12 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. |
