• Translation from original language as provided by authorSpintronics is a new emerging field of research at the cross of magnetism, electronics and informatics, etc. Using both electronic charge and spin, the spintronic devices have the advantage over traditional semiconductor electronic devices because of the nonvolatility, high-speed of data processing, low-consumption of power and considerable integration densities. At present, one of the key issues is to find spintronic materials with high spin-polarized conductive electrons, therefore, half-metals, of which the conductive electrons are 100% spin-polarized, would have potential applications in spintronics. Lots of materials have been theoretically predicted or experimentally proven to be half-metals. Among those materials, Heusler alloys are thoroughly studied. Besides, some new half-metallic ferromagnets, i.e., the IIA-VA, IA-IVA, IIA-IVA compounds with Zinc-Blende structure have been attrcted much attention. In this work, using the first-principle calcul
