Abstract Scope |
Some characteristics of amorphous nanocomposites that differentiate them from other soft magnetic materials include high saturation magnetic flux density (Bs), low magnetic loss, and high permeability (μ). Moreover, a wide range of B-H properties can be acquired through heat-treatment of the alloys in different conditions. In the present study, the magnetic and microstructural properties were investigated of nanocrystalline soft magnetic alloy with the composition of Fe80Si7B9Nb3Cu1 fabricated by the melt-spinning method. The longitudinal magnetic field annealing contributed to the uniform distribution of α-Fe nanocrystals. The lowest core loss (Pcv) was 124.0 mW/cm3 annealed at 560 ℃. Furthermore, the core annealed at 560 ℃ showed the enhancement in Bs with the value of 1.57 T as compared to the conventional value of FINEMET core (Bs = 1.23 T). The combination of high Bs with excellent magnetic properties makes this nanocomposite alloy an outstanding economical application in the high frequency (f) region. |
