Abstract: High-frequency magnetic properties, such as core loss, coercivity and amplitude permeability of a newly-developed nanocrystalline Fe72.5Cu1Nb2V2Si13.5B9 alloy in the wide ranges of f=20-1000 kHz, Bm=0.01-0.6T and Bmf=10-40 (T•kHz) have been measured. A large amount of experimental data have been fitted by a computer, thus obtaining several expressions representing the influence of frequency on high-frequency magnetic properties, that are useful in practical applications.
