Abstract

This paper reports an increase in the ability to absorb microwaves from a composite made of combination between soft and hard magnetic materials, perovskite material, and an epoxy as matrix of composite, Ni0.5Zn0.5Fe2O4/Ba0.6Sr0.4Fe9.5Al0.5MnTiO19/FeTiO3/epoxy (NBFE) with a wt% ratio of 5:3:2:10. Composite samples were made using the mechanical alloying method with milling techniques and sintered at a temperature of 1000 °C for 5 h. NBFE composites were studied to increase the ability to absorb microwaves at 2-18 GHz frequencies with thickness variations of 1 mm and 2 mm. The results obtained, the composite sample Ni0.5Zn0.5Fe2O4/Ba0.6Sr0.4Fe9.5Al0.5MnTiO19/FeTiO3/epoxy has the ability to absorb microwaves with the best reflection loss value −37.47 dB with a bandwidth almost reaches 11.32 GHz in the 2-18 GHz frequency range. © 2024 IOP Publishing Ltd.
