Description
Summary:Structural, magnetic, and electrical characteristics of La 1 −  x Sr x Mn 0.90 (Mg 0.5 Ge 0.5 ) 0.10 O 3 + γ (0.15  0) and La 0.91 Sr 0.09 Mn 0.90 Mg 0.10 O 3 , La 0.71 Sr 0.29 Mn 0.90 Ge 0.10 O 3 manganites are investigated and compared. A comparison of the properties of manganites with identical total concentrations of substituents for manganese and equivalent concentrations of Mn 4+ and Mn 3+ ions reveals several competing effects caused by Sr 2+ (4 p 6 ), Mg 2+ (2 p 6 ), Ge 4+ (3 d 10 ) ions and oxygen.
