Both the hyperfine fields and the easy magnetization magnitude are not correlated with the modulation characteristic length (lambda) while the magnetization perpendicular to the thin-film plane decreases as lambda increases. The spectra were recorded at room temperature being the gamma rays perpendicular to the substrate plane. The magnetization measurements were recorded by using a SHE SQUID magnetometer in applied magnetic fields up to 5.5 T and in the temperature range between 1.8 and 30 K.3 p.application/pdfeng(c) IEEE, 1988Efecte de MössbauerPropietats magnètiquesAliatgesSubstàncies amorfesPel·lícules finesInteraccions hiperfinesMossbauer effectMagnetic propertiesAlloysAmorphous substancesThin filmsHyperfine interactionsinfo:eu-repo/semantics/article43682info:eu-repo/semantics/openAccess
