| 中文摘要 | The origin of the Slater-Pauling curve M-t=Z(t)-28 (Here M-t is the total spin moment and Z(t) is the number of valence electrons) in half-metallic Heusler alloys Mn(2)CuZ (Z=Ge and Sb) has been studied in detail. In Mn(2)CuZ the half-metallic gap has a similar origin like half-Heusler alloys. The Cu atom acts as an electron "donator" in Mn(2)CuZ, which contributes five d-electrons to the minority spin band of Mn(2)CuZ. So there are 14 valence electrons in the minority band of Mn(2)CuZ below the Fermi level. This is the origin of the S-P curve M-t=Z(t)-28. Finally, it is found that, by partial doping of Cu to the vacant site of half-metallic half-Heusler alloys, the magnetic moments of these can be tuned without destroying the half-metallicity. This can be a possible way to design new half-metals. (C) 2012 Elsevier B.V. All rights reserved. |
