Highly stable dielectric frequency response of chemically synthesized Mn-substituted ZnFe2O4

摘要: Abstract The tenacity of the present study was to develop a material using an economical chemical route, having balance between magnetic and dielectric order parameters for maximum transmittance electromagnetic waves in use them shielding materials. In this context, Mn-Zn ferrites were prepared wet based sol-gel auto-combustion technique. X-ray diffraction confirmed pure phase formation samples, while some impurity peaks also higher value Mn substitution. Field emission scanning electron microscopy revealed decrease grain size with increasing While energy dispersive spectroscopy elemental composition substituted constant, loss tangent decreased frequency complex electric modulus found be function values increased impedance RC series circuit parallel both AC conductivity series. Dielectric response studied samples best match expected results. Nyquist Cole-Cole plots semi-conductive behavior at substitution yielded same relative stability used as materials Bode Nichols plots, comparatively high gain margin observed, well suitable potential applications shielding.
