Postoyannoe rasshirenie oblasti primeneniya zhelezosoderzhashchikh oksidov trebuet sozdaniya soedineniy s razlichnymi svoystvami. Mnogoobrazie kationnykh zameshcheniy v perovskitopodobnykh kristallakh otkryvaet bol'shie vozmozhnosti dlya polucheniya veshchestv s novymi svoystvami. V ramkakh nastoyashchego issledovaniya nami izucheny kristallicheskaya struktura i magnitnaya mikrostruktura redkozemel'nykh ortoferritov LnFe(2/3)Mo(1/3)O(3) (Ln = La, Ce, Pr, Nd) i slozhnykh oksidov s kislorod-defitsitnymi strukturami perovskita tipa 4-1-5 Pr(4)BaCu(5-kh)Fe(x)O(13-δ) (kh = 1, 1,5; δ = 0, 0,5), 8-8-20 Ln(8-y)Sr(y)Cu(8-kh)Fe(kh)O(20) (u = 1,6-4, x = 1,6-3, Ln = La, Pr, Nd) i 1-2-3 YBa(2-y)La(y)Cu(2,88)Fe(0,12)O(7-δ), Y(1-y)Sa(y)Ba(2-y)La(y)Cu(3-x)Fe(x)O(7-δ) (u = 0,25, 0,5; x = 0,06, 0,12; δ ≈ 0,5). Osnovnym metodom issledovaniya yavlyalas' messbauerovskaya spektroskopiya, takzhe ispol'zovalsya rentgenostrukturnyy analiz.
