Magnetic properties of nanocrystalline FeCuNb(Sb/W)SiB alloys

摘要

The magnetic relaxation /spl Delta/r/r, the perminvar critical field H/sub CR/, the initial susceptibility, /spl chisub 10/, the coercive field X/sub C/ as a function of annealing temperature in Fe/sub 73.5/Cu/sub 1/Nb/sub 2.95/Sb/sub 0.05/Si/sub 13.5/B/sub 9/ and Fe/sub 73.5/Cu/sub 1/W/sub 3/Si/sub 13.5/B/sub 9/ alloys were investigated. DSC measurements and thermomagnetic analyses were also done. The results can be explained using the random anisotropy model.
