Low Core Loss of a bcc Fe86Zr7B6Cu1 Alloy with Nanoscale Grain Size

We have investigated the possible applications potential of a newly developed bcc-nanocrystalline Fe 86 Zr 7 B 6 Cu 1 alloy by determining the core loss, permeability μ c , and magnetization B 800 (at a field 800 kA/m). The above parameters have been studied as a function of annealing temperature T a of the as-quenched amorphous alloy, maximum induction B m , and frequency (up to 100 kHz)
