%X Researches on manganese-zinc ferrite Mn0.8Zn0.2Fe2O4 got popular due to its good magnetic properties as a soft magnetic material. Studies on Mn0.8Zn0.2Fe2O4 magnetic properties, especially before and after the sinter-ing process, are required to see its magnetic material characterisation. Therefore, this research focused on manganese-zinc ferrite Mn0.8Zn0.2Fe2O4 characterisations using co-precipitation method with sintering time varia-tions of 3, 4, and 5 hours at 1100°C. Base materials used in this research were manganese oxide (MnO), zinc oxide (ZnO), and iron oxide (Fe2O3). XRD, SEM-EDX, and VSM tests were used to characterise phase, mor-phology, and magnetic properties. Mn0.8Zn0.2Fe2O4 with 3, 4, and 5 hours holding time sintering process resulted in crystallite size changed into 70.4194 nm, 52.91546 nm, and 26.45 nm. During the holding time of sin-tering process, the single Mn0.8Zn0.2Fe2O4 phase was formed, the materials were in one lattice, and it has cubic shape structures. Sintering process affects particle bulk size; a higher sintering temperature increases parti-cle bulk size. Materials with holding time sintered that formed a single Mn0.8Zn0.2Fe2O4 phase had higher magnetic retentivity compared to mate-rials before sintering. This is evident by magnetic saturation (Ms) and magnetic remanence (Mr) values that are higher than for materials with-out sintering. In 3 hours holding time sintering, the sample has a mag-netic saturation (Ms) of 54.05 emu/g and a magnetic remanence (Mr) 14.38 emu/g, higher than other variants. © 2019 G.V.
