New correlated model of colossal magnetoresistive manganese oxides.
A new minimal model is constructed for the doped manganese oxides which exhibit colossal magnetoresistance, involving a broad spin-majority conduction band as well as nearly localized spin-minority electron states. A simple mean-field analysis yields a temperature-dependent hybridized band structure with suppressed carrier weight at the Fermi level. Spin stiffness is complex, indicating strong ...
متن کاملTheory of colossal magnetoresistance
The history and recent developments in studying (colossal) magnetoresistance in perovskite manganese oxides is reviewed. We emphasize the growing evidence for strongly coupled spin, charge and lattice degrees of freedom. Together with disorder, these provide the microscopic driving forces for local and inhomogeneous textures. The modeling and experimental probes for localized charge–spin–lattic...
متن کاملMagnetic and Transport Properties Of
After the discovery of the high-Tc superconducting oxides, many strongly correlated 3d electron systems have been reinvestigated. Recently, perovskite-type manganese oxides (R,A)MnO3 have been studied extensively. The above group of materials exhibit colossal magnetoresistance (MR) at the carrier doped region, which is interesting not only from the standpoint of strongly correlated systems but ...
متن کاملNanoscale Phase Separation in Colossal Magnetoresistance Materials: Lessons for the Cuprates? ⋆
A recent vast experimental and theoretical effort in manganites has shown that the colossal magnetoresistance effect can be understood based on the competition of charge-ordered and ferromagnetic phases. The general aspects of the theoretical description appear to be valid for any compound with intrinsic phase competition. In high temperature superconductors, recent experiments have shown the e...
متن کاملAn investigation on layered birnessite type manganese oxides for battery applications
Layered birnessite-type manganese oxide was prepared by a simple redox sol–gel reaction involving hydroxylamine and permanganate in alkaline medium. IR, XRD, Auger electron spectroscopy, EPR, TGA and cyclic voltammetric characteristics of the birnessites are presented. The birnessite was examined for its cathode performance in zinc-, magnesiumand lithium-based cells. Bismuth and lead exchanged ...
