| Popis: | Polycrystalline ErxNi0.8Zn0·2Fe2-xO4 nanoparticles were synthesized using wet chemical route. Powder x-ray diffraction (XRD) data was utilized to observe the structural parameters. The cubic crystalline structure with the second phase was obtained from XRD patterns. Two significant absorption bands (between 700 and 400 cm−1) at the tetrahedral and octahedral sites were studied from Fourier transform infrared spectroscopy (FTIR) that further confirmed the spinel structure of prepared ferrites. These are the main bands of spinel ferrites. After the structural explanation, the dielectric, electrical and magnetic parameters were studied in detail at room temperature. All of these parameters were affected by Er3+ substitution. The obtained results suggested the possible utilization of these soft ferrites in advanced technological applications such as the devices working at high frequencies, magnetic data recording, switching applications, etc. |
