A new diluted magnetic semiconductor: The half-metallic ferromagnet CoTi_(1-x)Fe_xSb

摘要

C1_b compounds with 18 valence electrons are semiconducting. It will be shown that doping with electrons results in half-metallic ferromagnets, similar to the case of diluted semiconductors. CoTiSb is known to be a semiconducting C1_b compound. Doping by
