4 M ay 1 99 9 Anisotropy and temperature dependence of the optical conductivity in LaMnO

چکیده
A tight binding parameterization of the band structure, along with a mean field treatment of Hund, electron-electron, and electron-lattice couplings, is used to obtain the full optical conductivity tensor of LaMnO3 as a function of temperature. We predict striking changes with temperature in the functional form and magnitude of the optical absorption. Comparison of our results to data will determine the Hund, electron-lattice, and electron-electron interactions.

Using the Kondo lattice model with classical spins in infinite dimension, conductivity in the perovskite-type 3d transition-metal oxide (La,Sr)MnO3 is theoretically studied. Green’s functions as well as spontaneous magnetization are obtained exactly on the Bethe lattice as a function of temperature. Conductivity is calculated from the Kubo formula. Below the Curie temperature, resistivity as a ...
متن کاملAnisotropy in the ab-plane optical properties of Bi2Sr2CaCu2O8 single-domain crystals
The ab-plane optical properties of the high-temperature superconductor Bi2Sr2CaCu2O8 are anisotropic in both the normal and the superconducting state. Consistent with the orthorhombic structure, the principal axes lie along the a and b crystallographic axes, nearly 45° from the Cu-O bond direction. In the normal state, analysis of the temperature-dependent optical conductivity suggests a scatte...
متن کاملThe Temperature Dependence of Conductivity Anisotropy in Intermediately Doped Polyacetylene
The temperature dependence of electrical conductivity and conductivity anisotropy of FeCI3 doped stretch-oriented polyacetylene film at different doping levels were measured by using Montgomery technique. The increase of conductivity anisotropy upon doping is related to the aligned fibrillar structure and the interfibrillar contact effect. Weak temperature dependence, the slight decrease at low...
متن کاملMobility gap in intermediate valent TmSe
– The infrared optical conductivity of intermediate valence compound TmSe reveals clear signatures for hybridization of light d-and heavy f-electronic states with m * ≈ 1.6m0 and m * ≈ 16m0, respectively. At moderate and high temperatures, the metal-like character of the heavy carriers dominate the low-frequency response while at low temperatures (TN < T < 100K) a gap-like feature is observed i...
