Nanocrystalline (Fe1-xCox)90Zr7B2Cu 1 (0≤x≤0.6) alloys were investigated by x-ray diffraction, 57Fe Mössbauer spectroscopy, and magnetic measurements. The grain size did not change significantly with composition. Co was preferentially partitioned to the residual amorphous phase, and the bcc grains were accordingly enriched by Fe. The room-temperature coercive field increased with the Co addition, which is attributed to the increasing magnetostriction constant.
