## Abstract

The compositional dependence of the soft magnetic properties of the nanocrystalline Fe–Zr–Nb–B alloys has been investigated. The magnetostriction [formula omitted] and the grain size of the [formula omitted] alloys, which are two typical ternary alloys mixed with the best soft magnetic properties, show intermediate values between those of the [formula omitted] with negative [formula omitted] and the [formula omitted] with positive [formula omitted] However, the soft magnetic properties of the [formula omitted] alloys are inferior to those of the [formula omitted] and the [formula omitted] alloys. The best soft magnetic properties have been obtained at [formula omitted] The [formula omitted] alloy shows a high [formula omitted] of 60 000 at 1 kHz, a high [formula omitted] of 1.64 T, and zero [formula omitted] simultaneously. The alloy also exhibits a very low core loss of 0.09 W/kg at 1.4 T and 50 Hz, which is extremely lower than that of Fe–Si–B amorphous alloys. The nanocrystalline Fe–Zr–Nb–B alloys with improved soft magnetic properties are therefore suitable for pole transformers.
