Investigations on transport, impedance and electromagnetic interference shielding properties of microwave processed NiMg ferrites
Source abstract
Abstract
Abstract Microwave processed Ni 1-x Mg x Fe 2 O 4 with x = 0.0–1.0 are characterized fordc,ac conductivities and dielectric properties as a function of temperature and frequency. Very low dielectric loss tangent is achieved at 5 MHz frequency. Grain and grain boundary contribution towards conductivity is presented on the basis of Nyquist plots and their resistances are evaluated from semi-circular arcs. Equivalent electrical circuits and approximate R-C values are presented for better insight. High dielectric constant of 41 for x = 0.8 sample instigated the possibility of good electromagnetic absorption material. A shift in the transport phenomenon is suggested from band like to polaron hopping with rise in temperature.In addition the electromagnetic interference shielding properties are studied in X-band.The results show that the goodelectromagnetic interference shielding efficiency is achieved for x = 0.4 − 0.6 compositions ranging from 10 to 17 dB (at 8.4 GHz) which is suitable for shielding application.
