“…A wide spectrum of deposition techniques appear in the process of obtaining ferromagnetic layered structures, which include spin coating, chemical vapor deposition (CVD), ion sputtering, vacuum deposition, or pulse electroplating [3,7,10]. It is worth emphasizing that the spin coating method cannot guarantee a uniform coating thickness [15], and the layers obtained by CVD methods have low purity [18].…”

The paper presents the technology for obtaining NiFe/Ti/NiFe layer structures in MEMS technology using magnetron purge with the assumption of being used as semi-magnetic sensors. A series of samples was made on a glass substrate with a sandwich structure, where the individual layers were 100 nm NiFe, 10 nm Ti and on top again NiFe with a thickness of 100 nm. Measurements of DC resistance of the obtained structures in a constant magnetic field, which was produced by neodymium magnets and an electromagnet, were carried out. The obtained results confirm the occurrence of phenomena known as the magnetoresistance effect. The influence of the spatial arrangement of structures relative to the constant magnetic field vector was checked and proved.

“…Soft magnetic nanocomposites are interesting materials because of their use in high frequency device application in variety of devices including on-chip micro-inductor, read write heads, magnetic sensors and spin valves [1,2]. NiFe thin films have been extensively used in practical device application [3][4][5]. NiFe alloy films with a composition of Ni82Fe18 is well known as a soft magnetic material and called permalloy [6,7].…”

Soft magnetic thin films of NiFeCr were prepared using electrodeposition in various bath temperature. NiFeCr deposited films are textured with FCC phase preferred orientation. Experimentally observed soft magnetic property of thin films for different temperature was compared.The addition of chromium can enhance magnetic and mechanical properties of NiFe thin films. Electrodeposited NiFeCr films were prepared at different temperature (30, 50, 70 and 90 °C) and they were subjected to morphological, structural, magnetic and mechanical characterization analysis. Nickel content was maximum as 51.36 wt % at 90 °C. The chromium content increased when electrolytic bath temperature was increased. NiFeCr films were bright and uniformly coated on the surface. Also the deposits of NiFeCr films were in nano scale and the average crystalline size was around 30 nm. Thin films prepared at high temperature exhibited a high saturation magnetization and low coercivity. The micro hardness of NiFeCr was 272 VHN at 90 °C.

In this study, electroplated NiFeP thin films were prepared with different density of current. Characterization of films was analyzed. The X-ray diffraction investigation exhibits that the electro plated NiFeP thin films consist of a face-centered cubic (FCC) phase with diffraction peaks ( 220), ( 200) and ( 111). The EDAX study shows that the maximum nickel content of 80.81 wt% was received for the density of current 5 mA/cm 2 g/l. The weight % of ferrous decreases while a current density was raised. The SEM result exhibits that NiFeP thin films were shiny and uniformly deposited on the cathode surface. The Vickers Hardness Tester result shows that reduction in hardness by improving current density. Moreover, VSM studies indicate an increase in coercivity of materials and decrease in magnetization by increasing current density.
