“…The reduction in thermal expansion of ferrous nickel alloys confirms mechanical stability with the ceramic substrates, semiconducting devices and glass windows on packaging. Magnetic materials can be deposited on the substrate using several methods [10][11][12][13][14] . Electro deposition is a important growth technique involving the materials deposition from an electrolyte bath by passing electric current at particular temperature and pressure.…”

In this paper, electroplated NiFe-P have been prepared and studied with different concentration of ferrous. The X-ray diffraction analysis demonstrates that the electrodeposited NiFeP thin films consist of face centered cubic phase with diffraction peaks (220), (200) and (111). The EDAX analysis confirm that the maximum nickel content of 74.49 wt% was obtained for ferrous concentration 10 g/L. The weight percentage of ferrous increased while ferrous concentration was increased. The SEM result shows that NiFe-P thin films were bright and uniformly coated on cathode surface. The Vicker Hardness Tester analysis shows that increases in hardness by increasing ferrous concentration. Also VSM studies shows decrease in coercivity and increase in magnetization were achieved by increasing ferrous concentration.

Nickel, iron films are vitally used in new generation recording heads, designing of microelectro mechanical devices and magnetic random access memory. The addition of tungsten (W) can enhance magnetic and mechanical properties of NiFe thin films. Electrodeposited Ni-Fe-W films were prepared at different temperature (30, 50, 70 and 90 0 C) and they were subjected tomorphological, structural, magnetic and mechanical characterization analysis. Nickel content was maximum as 61.41 wt% at 90 o C. The tungsten content increased when electrolytic bath temperature was increased. Ni-Fe-W films were bright and uniformly coated on the surface. Also the deposits of Ni-Fe-W films were in nano scale and the average crystalline size was around 22 nm. Thin films prepared at high temperature exhibited a high saturation magnetization and low coercivity. The micro hardness of Ni-Fe-W was 221 VHN at 90 o C.

Spirulina platensis were chosen as templates to produce microscopic helical soft-core magnetic particles by way of depositing ferromagnetic alloy onto their surface using electroplating technique, and the process of electroplating ferromagnetic alloy onto microorganism cells was studied. The morphology and appearance of the coated Spirulina platensis were analyzed with optical microscopy and scanning electron microscopy, respectively, and the ingredients and phase structure of the alloy coating were analyzed with energy dispersive X-ray detector (EDX) and X-ray diffractive analysis (XRD), respectively. The result showed that the particles were successfully coated with uniform metal coating and their initial helical shape was perfectly replicated. The coating was NiFe alloy, and its phase structure was face-centered cubic structure. The magnetic properties of the coated particles were tested with vibrating sample magnetometer (VSM), and the result showed that the particles were ferromagnetic, which means the magnetic electroplating of the microorganism cells was successfully achieved. The electrochemical reaction mechanism of the magnetic plating process was also analyzed; the result showed that the deposition of NiFe on the microorganism cells was anomalous codeposition, and that Fe 2+ ion was preferential deposited when magnetic stirring was applied. bio-limited forming, microorganism, helical particles, electroplating, magnetic metallization Citation: Cai J, Zhang D Y, Lan M M, et al.
