Ushbu tezisda FeBO₃:Mg kristallida magnit tartib davrining — Néel haroratining (TN) — tashqi yorug’lik ta’siriga bog’liqligini tavsiflovchi nazariy model taqdim etiladi. Model magniy ionlarining Fe³⁺ ionlarini almashtirishi natijasida yuzaga keladigan superalmashinuv integral’ o’zgarishi va yorug’lik induksiyalagan spinorbital energiya hissasiga asoslanadi. Model bashoratlarining mavjud eksperimental ma’lumotlar bilan mosligi tahlil qilinib, Mg konsentratsiyasining optimal diapazoni aniqlanadi.
