State of atoms and interatomic interactions in complex perovskite-like oxides: XXXVI. Magnetic susceptibility of LaFexGa1–xO3 and La1–0.2xSr0.2xFexMg0.2xGa1–1.2xO3 solid solutions

Resumo

Magnetic susceptibility of solid solutions based on lanthanum gallate doped with iron, and also with iron, strontium, and magnesium in the ratio 5 : 1 : 1 was studied. In both systems at the infinite dilution clusters of iron atoms remain, the fraction of these clusters in lanthanum gallate doped only with iron comprising 0.4 of the total fraction of clusters in the gallate doped with strontium and magnesium.
