| Summary, etc | Magnetic nanoparticles and nanocrystalline thin film have attracted enormous research<br/>interest during the last few decades due to wide spread applications of these materials in<br/>advanced optoelectronic, magnetic and bio devices. Chemical Bath Deposition Technique<br/>being a simple and cost-effective method has been adopted to produce nanocrystalline<br/>thin films and powder of iron oxide. The deposition methodology was optimized to<br/>achieve homogeneous growth of nanostructures. The iron oxide nanostructures and<br/>deposited thin films have been further characterized by X-ray diffraction, Scanning<br/>Electron Microscopy, Energy Dispersive X-ray (EDX) and Vibrating Sample<br/>Magnetometer (VSM) techniques in order to investigate their structural, morphological<br/>and magnetic properties, respectively. XRD patterns revealed that deposited thin films<br/>and powder exhibit polycrystalline structure with cubic phase. Broader diffraction peaks<br/>confirmed the growth of nanocrystals in all samples. Crystallite size was estimated by<br/>Scherer’s equation and found to be 3.18 and 0.60 nm for powder sample and thin film,<br/>respectively. Morphology analysis revealed that grains are grown with variable size in<br/>both samples i.e. powder and thin film. For powder samples, grains with size ranging<br/>from 16 to 100 nm and for thin film samples, grains with size ranging from 5 to 60 nm<br/>have been observed. Almost uniform growth of clusters which are distributed throughout<br/>the substrate surface in case of thin films demonstrated the controlled growth of<br/>nanostructures. EDX analysis confirmed the presence of essential precursors with desired<br/>stoichiometry in all samples. Magnetic properties (M-H curves) of the samples revealed<br/>that saturation magnetization of powder and thin film has the value of 2.1x10-5 and<br/>6.2x10-3 emu, respectively. Magnetite nanoparticles show more coercivity and retentivitiy<br/>as compared to that of thin film. These nanostructured thin films might have potential<br/>applications in advanced magnetic and recording materials. |
