Tokyo), Yutaka Moritomo (CIRSE, Nagoya Univ.), K. Hirota and Y. Endoh (Tohoku Univ. | | Abstract: | Scaling relations in the charge and spin excitations of (La,Sr)MnO3 are studied from both theoretical and experimental points of view. In the ferromagnetic metal phase, we investigate optical conductivity and neutron inelastic scattering, and compare with a theoretical calculation based on the dynamical mean-field theory of the double-exchange hamiltonian. Spin and charge dynamics of (La,Sr)MnO3 exhibit typical behaviors of half metals. In these manganite compounds with high Curie temperature, various behaviors in spin and charge properties are explained by the double-exchange hamiltonian alone. Magnetoresistance of these compounds as well as other compounds with lower Curie temperature are also discussed. | | Source: | arXiv, cond-mat/9808076 | | Services: | Forum | Review | PDF | Favorites | |
