Magnetic properties of ultrasoft-nanocomposite FeAlSiBNbCu alloys
The effects of up to 10 at% substitution of Fe by Al on the microstructure and DC and AC magnetic properties of nanocrystalline FeSiBCuNb alloy ribbon are summarised and analysed. The minimum DC H c developed during annealing decreases by 40% for 2 at% Al (to 0.3 A/m) and remains roughly constant fo...

Summary: | The effects of up to 10 at% substitution of Fe by Al on the microstructure and DC and AC magnetic properties of nanocrystalline FeSiBCuNb alloy ribbon are summarised and analysed. The minimum DC
H
c
developed during annealing decreases by 40% for 2 at% Al (to 0.3
A/m) and remains roughly constant for larger Al contents. The largest peak value of
μ
0.4
at 50
Hz also corresponds to 2 at% Al. The best frequency response for
μ
0.4
occurs for 6 at% Al while there was no improvement in AC power loss behaviour over the 0% Al alloy. The improvements in DC
H
c
and AC
μ
0.4
are ascribed to a reduction in
K

of the Fe–Si-based nanocrystallites by the introduction of Al. |
