Introduction Ni-Fe plating has a copmpact structure, bright and smooth surface and was widely used in the production of new materials that require specific mechanical, chemical and/or physical properties[1,6].
In the present work, we investigated several important factors on the nickel-iron plating composition and electromagnetic property.
Experimental method Since the magnetic properties of Ni-Fe alloys are seriously affected by their compositions and structures, a reliable control of the composition and textural properties (e.g. crystalline structures, morphologies, roughness, etc.) through plating is an important issue in designing the magnetic functionality of these materials.

Introduction TiO2 has many outstanding optical, electrical and photocatalytic properties which make it suitable for many industrial applications such as anti-bacterial, waste purification, self cleaning, and solar cells [1].
Among thin film processes, such as thermal oxidation of metal, sol–gel coating, electron-beam evaporation, and sputtering [2-5], the use of a radio frequency (RF) magnetron sputtering provides more benefit in controlling the structure, composition and properties of TiO2 films due to the ease of adjusting deposition conditions, resulting in higher deposition rate [6].
