The purpose of this study is to obtain high-entropy oxides with the magnetoplumbite structure, in which the Pb cation is used as a divalent metal cation. The synthesis conditions were optimized, and a technique was developed to avoid the evaporation of lead oxide. For the first time, single-phase samples of high-entropy oxides with the magnetoplumbite structure were obtained, its chemical composition is reflected by the formula PbFe$_{2.4}$X$_{2.4}$Y$_{2.4}$Ga$_{2.4}$In$_{2.4}$O$_{19}$. The particle size of the high-entropy phase is about 100 nm, which makes it promising for a number of applications. The effect of preliminary grinding of the initial components on the results of synthesis was studied. A synthesis mechanism is proposed. The results pave the way to synthesis and study of the properties of a new large subgroup of high-entropy oxides with the magnetoplumbite structure, which expands the possibilities of controlling the properties of ceramic magnetic materials.
Keywords: high-entropy oxides, magnetoplumbite, lead, nanocrystals, synthesis, magnetic materials.
