Abstract
Structural, magnetic, and electrical characteristics of La1 – xSrxMn0.90(Mg0.5Ge0.5)0.10O3 + γ (0.15 x 0.30, γ = 0, γ 0) and La0.91Sr0.09Mn0.90Mg0.10O3, La0.71Sr0.29Mn0.90Ge0.10O3 manganites are investigated and compared. Comparison of the properties of manganites having identical summary concentrations of substituents for manganese and equivalent concentrations of Mn4+, Mn3+ ions revealed several competing effects caused by Sr2+(4p6), Mg2+(2p6), Ge4+(3d10) ions and oxygen.
