Structural and Dielectric Studies of Samarium Substituted Cobalt Nano Ferrites
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 3
Abstract
The Samarium Substituted Cobalt Nano Ferrites With Chemical Formula Cosmxfe2-XO4 (Where X=0.0, 0.010, 0.030, 0.050, 0.070, 0.090 And 0.10) Were Synthesized By Citrate-Gel Auto Combustion Method. Synthesized Powders Were Sintered At 5000C For Four Hours In Air And Characterized By XRD, SEM, EDS, FTIR. X-Ray Diffraction (XRD) Analysis Showed Cubic Spinel Structure Of The Ferrites And The Values Of Lattice Constant (A) And X-Ray Density (Dx) Increased With The Increase Of Sm Content. The Surface Morphology Of The Samples Was Observed By Scanning Electron Microscopy (SEM). An Elemental Composition Of The Sample Has Studied By Energy Dispersive Spectroscopy (EDS). The Observed Results Can Be Explained On The Basis Of Composition. The Dielectric Parameters Like Real Part Of Dielectric Constant(Εʹ), Imaginary Part Dielectric Constant (Εʺ) Of The Samples Were Studied As A Function Of Frequency In The Range Of 50Hz To5mhz At Room Temperature Using Agilent E4980 Were Studied. The Observed Result Can Be Explained On The Basis Of Conduction Mechanism.
