- W74900275 abstract "The authors studied the electronic structure and optical properties of the low temperature (T = 0 K for the calculation) ferromagnetic phase of La[sub 3/4]Ca[sub 1/4]MnO[sub 3] using a self-consistent ab-initio LCAO method. The authors employed a local density potential. The calculated electronic structure suggests that the material is in a half-metallic state. The calculated average magnetic moment for the half-metallic phase is 3.75 [mu][sub B] per Mn. This value is very close to the experimental values of 3.7 [mu][sub B] per Mn. The real part of the optical conductivity, [sigma][sub 1]([omega]), from the direct band transitions, is predicted. The calculated optical conductivity shows that for photon energies below 2.4 eV, the electronic states of minority spin do not contribute to the optical transitions." @default.
