A Theory of Perovskite-Type Manganites (La,M(II))MnO₃, 1954 November 30
Scope and Contents
MIT DIC 6889. Project Whirlwind Memo 6M-3185. Semicovalence and its effects on indirect magnetic-exchange interaction are reviewed and applied to the manganites. These considerations lead to qualitative predictions which are in complete accord with the following experimentally observed facts, where x is taken as the percentage of manganese ions which are Mn[superscript 4+]: (1) At x = 0, LaMnO₃ is an orthorhombic perovskite-type lattice with a₁ = a₃ > a₂. The ratio a₂/a₃ increases to 1 at x = 1/4, and for 0.4root>
