With the aim of developing good soft magnetic materials, we examined the magnetic properties of nanocrystalline Fe-M-B alloys containing various additional elements. The nanoscale bcc Fe-Zr-Nb-B-Cu alloys exhibited excellent soft magnetic characteristics of 1.5 to 1.6 T for saturation magnetization (Bz), 1 to 2 A/m for coercive force (Hc), 10×104 to 12×104 for permeability (μe) at 1 kHz and nearly zero saturated magnetostriction (λ5) which had not been achieved for soft magnetic materials reported up to date. The excellent soft magnetic characteristics have already enabled the practical use as pulse transformers for portable telephones which require high μe above 105 at 1 kHz and high Bz above 1.5 T. The application fields are hereafter expected to increase significantly because of the excellent soft magnetic properties which have been obtained only for the present materials.
