Abstract
ZnFe2O4 nanomaterials were prepared using a solid-state reaction method using high energy milling (750 rpm) for 30 hours and calcined at 1000°C for 5 hours. The characterizations used include XRD, SEM, VSM, and VNA. The measurement results show that the sample has a single phase with a cubic structure. The surface morphology of heterogeneous samples with a particle size of 250-400 nm shows magnetic performance with Ms 2.38 emu/g and Hc 11.29 kOe. The sample also can absorb electromagnetic waves in the frequency range of 2-18 GHz with a minimum RL value of ~-18.79 dB at a frequency of 3.66 GHz, while RL ~-13.32 dB has a bandwidth of 0.9 GHz.
