CEMS and RF-Mössbauer Study of Nanocrystalline Fe81Zr7B12Alloy

The combined conversion electron (CEMS) and 7-transmission Mössbauer spectroscopy is used to investigate the differences in the bulk and surface crystallization of the amorphous Fen Zr7B12 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-Mössbauer experiment permits us to distinguish soft magnetic nanocrystalline bcc-Fe phase from microcrystalline α-Fe.
