Article Preview

Nickel-Iron nanocrystalline alloys with different grain sizes were fabricated by electrodeposition technique. In this study, influence of the grain size nanocrystalline NiFe deposits on saturation magnetization Ms and coercivity Hc was investigated. Alternating gradient magnetometer (AGM) with up to 10 kOe applied magnetic field was used to study the magnetic properties of NiFe film. The results showed that saturation magnetization Ms and coercivity Hc were affected by grain size variation. Increase in grain size increased the saturation magnetization. The largest grain size of 18.6 nm showed the highest Ms of 138 emu/g, while the smallest grain size of 7.2 nm showed Ms of 94 emu/g. Minimum coercivity of 3.847 Oe was observed for sample with 7.2 nm grain sizes. The coercivities decreased for smaller grain sizes.
