    Atom probe field ion microscopy was employed to investigate the distribution of Al in a nanocrystalline Fe88Zr7B3Al2 soft magnet with optimal magnetic performance. The atom probe concentration depth profiles show that the Al atoms preferentially partition into the residual amorphous phase, and the partitioning factor of Al is approximately five times larger in the amorphous phase than in the bcc Fe phase. Based on the experimental results, the beneficial effect of the addition of Al on the soft magnetic properties is attributed to the change of the inherent magnetostriction constant of the residual amorphous phase induced by Al partitioning.
