Abstract
This research explores the effect of graphene nanoplatelets (GNPs) on structural, electrical, magnetic and dielectric properties along with surface morphology of CoZnNd ferrites (CZNF), synthesized through sol-gel auto combustion route. The results exhibited that CZNF particles were dispersed on GNPs, which modified the structural and electromagnetic characteristics of CZNF. Moreover, SEM micrographs revealed the reduction in agglomeration with inclusion of GNPs. Additionally, resistivity was increased in the ferro region and decreased in the para region with rising temperature. TCR for CZNF/2.5 wt %GNPs composite was recorded as −3.49% at 371 K. Excellent magnetodielectric properties were observed for CZNF/2.5 wt %GNPs composite, i.e. Ms = 141.76 emu/g and Hc = 81.2 Oe along with minimum Tan δm and skin depth. On the basis of studied parameters, CZNF/2.5 wt %GNPs composite is appropriate for high frequency micro wave shielding applications, inductors, filters, bolometers and switching devices.
