摘要
Density functional calculations are used to investigate the relationships among lattice distortions, magnetic ordering, and electronic properties in manganite perovskites. Distortions open narrow pseudogaps at the middle of the majority e(g) manifold. The effect on transport is very dependent on doping and falls off as divalent ions replace La in LaMnO3. Distortions in the ferromagnetic ordered colossal magnetoresistance regime are weakly coupled to electronic properties relative to pure LaMnO3. (C) 1998 American Institute of Physics.
