Complex orbital state in manganites
The eg-orbital states with complex coefficients of the linear combination of x2 − y2 and 3z2 − r2 are studied for the ferromagnetic state in doped manganites. Especially the focus is put on the competition among uniform complex, staggered complex, and real orbital states. As the hole-doping x increases, the real, the canted complex, and the staggered complex orbital states appears successively....

متن کاملQuantized spin waves in the metallic state of magnetoresistive manganites.
Spin wave measurements have been carried out in ferromagnetic (F) La(1-x)(Sr,Ca)(x)MnO(3) with x(Sr) = 0.15, 0.175, 0.2, 0.3, and x(Ca) = 0.3. In all q directions, close to the zone boundary, the spin wave spectra consist of several energy levels, with the same values in the metallic and the x approximately 1/8 doping ranges. For x(Sr) = 0.15, the data are quantitatively interpreted in terms of...
متن کاملOrbital Effects in Manganites
We review some aspects related to orbital degrees of freedom in manganites. The Mn ions in these compounds have double orbital degeneracy and are strong Jahn-Teller ions, causing structural distortions and orbital ordering. We discuss ordering mechanisms and the consequences of orbital order. The additional degeneracy of low-energy states and the extreme sensitivity of the chemical bonds to the...
متن کاملMagnons in ferromagnetic metallic manganites.
Ferromagnetic (FM) manganites, a group of likely half-metallic oxides, are of special interest not only because they are a testing ground for the classical double-exchange interaction mechanism for the 'colossal' magnetoresistance, but also because they exhibit an extraordinary arena of emergent phenomena. These emergent phenomena are related to the complexity associated with strong interplay b...
