We studied the electronic structure and optical properties of the low temperature (T = 0 K for the calculation) ferromagnetic phase of La3/4Ca1/4MnO3 using a self-consistent ab-initio LCAO method. We 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 μ B per Mn. This value is very close to the experimental values of 3.7 μ B per Mn. The real part of the optical conductivity, σ1(ω), 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.

The electronic structures of the titanium-doped cubic perovskite ruthenates BaRu1-xTixO3 with x=0.125, 0.25, 0.375, 0.5, 0.625, 0.75, and 0.875 are investigated using the spin-polarized density functional theory within the pseudopotential plane wave method. It is found that a half-metallic phase appears in the 0.75- and 0.875-doped systems, and the origin of half-metallic property is the decrease of t2g bandwidth of Ru 4d states with the increase in x. In addition, the energy gap of BaRu0.25Ti0.75O3 is as large as 1.7 eV at the Fermi level in the up-spin density of states, which suggests a stable half-metallic phase can be obtained in the present systems.
