This study aims to determine the magnetic properties and structural properties of zinc ferrite (ZnFe2O4) 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. ZnFe2O4 material was sintered with temperature variations of 950oC, 1050oC, and 1150oC 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 ZnFe2O4 material had an irregular cubic shape and the highest agglomeration was at ZnFe2O4 temperature of 950oC. 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. ZnFe2O4 with a sintering temperature of 1150oC in this study has the potential to be used as a microwave device. © 2023 Trans Tech Publications Ltd, Switzerland.
