Electrical Permittivity and Magnetic Permeability of FeR (original) (raw)
In this work, (FeR 3 ROR 4 Rand NiR 2 ROR 3 R) Nano-material thin films were deposited on ITO glass substrate, ten samples were prepared by sol-gel method with deferent concentrations (55.25, 78.7, 90.9 144.9 and 263.15) mg/cmP 2 P for each nano-material. The Nano crystal size of the deposited was found by the XRD technique. The UV-VIS spectrum was used to find refractive index and electric permittivity. The magnetic permeability was found by using the relation between refractive index and electric permittivity beside magnetic permeability. For FeR 3 ROR 4 R the electric permittivity and magnetic permeability were shown to increase when the concentration of Nano crystal decreases. However for NiR 2 ROR 3 R the electric permittivity and magnetic permeability increases upon increasing the molecular concentration. Introduction Nickel Oxide (NiO) is an important transition metal oxide with cubic lattice structure. Among the magnetic nanoparticles, fabrication of nickel nanoparticles (NPS) is often more difficult than that of the other particles. This is because they are easily oxidized. To achieve pure nickel nano-crystals, numerous methods have been conducted in organic environments in order to prevent formation of hydroxide or oxidation [1].Iron oxide nanoparticles (NPs) have attracted much consideration due to their unique properties, such as super paramagnetic, surface-to-volume ratio, greater surface area, and easy separation methodology. Various physical, chemical, and biological methods have been adopted to synthesize magnetic NPs with suitable surface chemistry [2]. The magnetic field strength and flux density are related to (Magnetic flux density in a material dependence on permeability and magnetic field strength) to each other. The proportionality constant is called the permeability, which is a property of the specific medium through which the H field passes and in which B is measured. The permeability has dimensions of Weber per ampere-meter (Wb/A m) or henries per meter (H/m) [3, 4]The permeability or relative permeability of a material is a measure of the degree to which the material can be magnetized, or the ease with which a B
