Epitaxial thin films of iron oxides with high spin polarization were fabricated using pulsed laser deposition toward the spin rectifying devices. Single crystalline-Si-substituted Fe2O3 thin films were formed using two-step laser ablation technique. They exhibited ferromagnetic behavior and spin polarization of 31% at room temperature. We also succeeded in fabricating the epitaxial thin films of p-type transparent Si:FeO using pulsed laser deposition. In the double layer structure of Fe3O4/Si:FeO, spin-polarized carriers were injected into the Si:FeO layer from the Fe3O4 ferromagnetic layer at room temperature.
