The C Band Frequency Absorption Based on Super-Paramagnetic Zn<sub>0.8</sub>Ni<sub>0.2</sub>Fe<sub>2</sub>O<sub>4</sub> Ferrite Nanoparticles

In this study, the absorption in the C band frequency range based on the super-paramagnetic Zn 0.8 Ni 0.2 Fe 2 O 4 ferrite nanoparticles was synthesized simultaneously, with the PEG. The X-ray Diffraction (XRD) was used to determine the structure of ferrite, Transmission Electron Microscope (TEM) indicated the spherical morphology and the average size of particles was approximately 7-8 nm, respectively. Additionally, the Vibrating Samples Magnetometer (VSM) revealed that the magnetization saturation M s of samples reached the highest value (28.47 emu/gr) with 0.15g/5ml PEG concentration. The high absorption of super-paramagnetic Zn 0.8 Ni 0.2 Fe 2 O 4 ferrite nanoparticles (98% power attenuation) with composite (carbon black and 6g super-paramagnetic Zn 0.8 Ni 0.2 Fe 2 O 4 ferrite) was investigated.
