To increase the saturation magnetization (Ms) of commercially available soft magnetic Finemet alloys to the level comparable to that of Si-steel and Fe-based nanocrystalline alloys such as Nanoperm, Nanomet, the B or Si content in combination with annealing heat treatment was tailored. The ribbons of Fe95−xSi1BxNb3Cu1 (x = 11, 12, 13) and Fe87−xSixB9Nb3Cu1 (x = 6, 8, 10) were prepared by melt-spinning and annealed at different temperatures to develop nanocrystalline microstructure optimizing the soft magnetic properties. The magnetic properties of the as-spun and annealed ribbons were measured using a vibrating sample magnetometer and AC B-H loop tracer to acquire Ms of above 1.4 T in all as-spun ribbons. Among the alloys, Fe84Si1B11Nb3Cu1 annealed at 545 °C showed the highest Ms of 2 T, which exceeds that of the conventional Finemet and other Fe-based nanocrystalline alloys.

Fe83.5B15Cu1.5Cax (x= 0.04, 0.07, 0.1 and 0.13) alloy ribbons were fabricated by melt spinning. The effects of Ca addition on electrical resistivity and soft magnetic properties were investigated. The results show that with increasing Ca content from 0.04 to 0.13 the electrical resistivity monotonously increases from 0.51 μΩ·m to 0.99 μΩ·m while the core loss reduced by 39% and 28% at 10 kHz and 20kHz under an applied magnetic field of 200 mT, respectively. After annealing at 420°C for 10min, sample with x=0.13 obtains the peak saturation induction density (Bs) of 1.82 T and coercive force (Hc) of 18 A/m. Especially, the core loss of sample x=0.13 decreased by 13% and 34% than that of x= 0.04 at 200 kHz under an applied magnetic field of 25 mT and 50 mT respectively. Therefore, the soft magnetic properties and core loss can be tuned by addition of Ca in Fe-B-Cu alloy ribbons.
