Influence of particle size distribution on magnetic properties of nanocrystalline soft magnetic Fe/sub 86/Zr/sub 7/Cu/sub 1/B/sub 6/

The effect of particle size distribution on the magnetic properties of nanocrystalline Fe/sub 86/Zr/sub 7/Cu/sub 1/B/sub 6/ samples is studied in detail. The analysis applies a realistic particle size distribution, obtained from transmission electron microscopy images, to the recently developed extended Random Anisotropy Model. The effect of a broad size distribution is found to be more relevant when the tail of the distribution is larger than 20 nm.
