The authors study the formation of crystals of Fe-Ga oxides and Fe–Ga–Cu borates in a multicomponent flux system based on Bi₂Mo₃O₁₂–Na₂B₄O₇. The Curie–Weiss temperature (θ_CW = 289 K) and the temperature of the ferrimagnet–paramagnet phase transition (T_C = 288 K) are determined from the electron spin resonance (ESR) spectrum and the magnetization of an Fe_1.1Ga_0.9O₃ single crystal, depending on temperature. Lines of spin-wave resonance are observed in the spectrum of magnetic resonance in the ordered phase.
