Abstract

Electronic and magnetic properties in the colossal magnetoresistive manganites are governed by the interplay between spin, charge, orbital, and lattice degrees of freedom. Especially in the moderately or highly hole-doped region around x = 1/2, the correlations of orbital and charge appear to dominate electronic and magnetic properties, and various electronic phases associated with orbital ordering emerges. Even in the ferromagnetic metallic state of La1-xSrxMnO3 with the maximal bandwidth, the orbital degree of freedom as a hidden parameter makes the charge dynamics anomalously incoherent, together with the generic coupling with dynamical lattice distortion.
