Abstract: The sequence of phase transformations during the crystallization of Sr$_{1,5}$La$_{0,5}$FeMoO$_{6-\delta}$ was investigated by the solid-phase reactions method. It has been established that in order to effectively minimize the influence of intermediate reaction products, it is advisable to use precursors and combined heating modes. As a result, it was possible to obtain the single-phase Sr$_{1,5}$La$_{0,5}$FeMoO$_{6-\delta}$ powder with the Curie temperature of $450$ K and a magnetization value of $40.9$ A$\cdot$m$^2\cdot$kg$^{-1}$ at $T = 77$ K in the magnetic field of $0.86$ T.

Keywords: lanthanum-strontium ferromolybdate solid solution, thermogravimetric analysis, X-ray phase analysis, crystallization rate, sequence and degree of phase transformations, magnetization.
