Abstract
The microstructure and magnetic properties of the amorphous and partially crystallized
Fe77-x-yCuxNbySi13B10 (x=0 or 1 and y=0, 1, 2 or 3)
ribbons were investigated. From Mössbauer spectroscopy investigations it was stated that the half linewidth
in Zeeman sextets corresponding to very fine α-FeSi grains is larger than that observed in the crystalline
alloys which is caused by the interface effect. Moreover, the off-plane anisotropy is observed after
annealing the Fe75Cu1Nb1Si13B10 ribbon at 693 K.
This may be attributed to the nucleation of α-FeSi grains in the ribbon surface.
The excellent soft magnetic properties were obtained for the Fe-based nanocrystalline alloy with additives
of 1 % Cu and 2 or 3% of Nb.
