Abstract 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 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 at 50 Hz also corresponds to 2 at% Al. The best frequency response for μ 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 and AC μ are ascribed to a reduction in K of the Fe-Si-based nanocrystallites by the introduction of Al.
