Title: Fabrication of Zinc Ferrite (ZnFe<sub>2</sub>O<sub>4</sub>) by Sonochemical Methods: Physical and Magnetic Properties in Various Temperatures
Abstract: This study aims to determine the magnetic properties and structural properties of zinc ferrite (ZnFe 2 O 4 ) material with the sonochemichal synthesis method. The sonochemichal method was obtained by sonication lasting for 30 minutes with the addition of 100 ml of 10 M NaOH. ZnFe 2 O 4 material was sintered with temperature variations of 950°C, 1050°C, and 1150°C with a holding time of 2 hours. Phase identification revealed that the cubic phase structure of zinc ferrite is franklinite and also obtained crystal size results with values of 70.58 – 84.71 nm. Morphological identification revealed that the ZnFe 2 O 4 material had an irregular cubic shape and the highest agglomeration was at ZnFe 2 O 4 temperature of 950°C. Identification of functional groups using FTIR characterization resulted in the wavelength range of 400-600cm -1 having basic lattices of Fe-O and Zn-O which occupy tetrahedral and octahedral positions, respectively. Magnetic identification uses VSM characterization which results that the sample is softmagnetic and gets several Mr, Ms, and Hc values. ZnFe 2 O 4 with a sintering temperature of 1150°C in this study has the potential to be used as a microwave device.
