The temperature dependencies of the effective saturation magnetostriction {lambda}{sub s}(T) of nanocrystalline Fe{sub 76.5{minus}x}Cu{sub 1}Nb{sub x}Si{sub 13.5}B{sub 9} (x = 2, 3 and 5) ribbons were measured for the samples which were annealed at 480, 500, 520 and 530 C. The nanostructure of the samples were characterized using X-ray diffraction measurements. In Fe{sub 76.5{minus}x}Cu{sub 1}Nb{sub x}Si{sub 13.5}B{sub 9} (x = 2, 3 and 5) no change of sign of the effective magnetostriction was found. On the contrary Fe{sub 73.5}Cu{sub 1}Nb{sub 3}Si{sub 16.5}B{sub 6} ribbon annealed at 530 C, shows at elevated temperatures a compensation point in {lambda}{sub s}(T). The authors suggested two mechanisms to explain this behavior: (a) for low concentration of Si in bcc-FeSi crystallites, the negative magnetostriction was not still reached; (b) for higher concentration, the Curie temperature enhancement of the amorphous matrix must be considered.
