The substituted U-type ferrite showed a dominant crystal structure at a different substitution ratio of manganese and zinc. The change of the starting temperature of U-type ferrite formation according to substitutional elements was confirmed by TG-DTA analysis. In the case of manganese substitution, the starting temperature of U-type ferrite formation lowered, and on the contrary, when zinc was substituted, it became higher. The magnetic properties of the U-type ferrite substituted with manganese showed a tendency that the saturation magnetization was decreased and the coercivity was increased as the manganese ratio increased. The highest saturation magnetization was 57.9 emu/g in the specific composition (Ba4Co0.5Zn1.5Fe36O60) substituted with zinc.}, type={Artykuły / Articles}, title={Study on Magnetic Properties of the U-Type Ferrite According to Substituted Elements}, URL={http://journals.pan.pl/Content/111307/PDF/AMM-2019-2-10-Kim.pdf}, doi={10.24425/amm.2019.127567}, keywords={U-type ferrite, hexagonal ferrite, sol-gel process}, }
