|Title:||Circular Magnetic Dichroism In Fe78-xnixsi8b14 (15≤x≤58) Ferromagnetic Amorphous Ribbons|
De Castro A.R.B.
|Abstract:||Fe78-xNixSi8B14 (15≤x≤58) amorphous ribbons were investigated by means of macroscopic magnetic characterization and X-ray magnetic circular dichroism (XMCD). The XMCD spectra were taken at the K and L edges of Fe and Ni, from which several indications of the local magnetic character of the alloy can be inferred. In both configurations, the spectra at Ni-edges display the same typical characteristic observed near Fe-edges, indicating that the amorphous alloy still behaves as a weak ferromagnet, with unfilled majority d-bands. © 2001 Elsevier Science B.V.|
