Spin-resolved photo-emission spectroscopy as well as the super-conducting point cotact technique have revealed the half-metallic nature of perovskite manganites, La_<0.7>Sr_<0.3>MnO_3, and CrO_2. In these half-metallic compounds, only one spin channel is metallic, while the other is insulating. With these materials, new spin electronics devices that rely on the spin polarization of the carriers would be realized. In this article, we explain the synthesis, crystal struccture, electronic structure, and physical properties of these half-metallic materials, and refer to the possibility of spin electronics devices.
