摘要：

The effect of alloying on the half-metallicity and magnetism of Co2Cr1-xMnxSi alloys (x=0-1) is studied using full-potential linearized augmented plane wave method. The calculations indicate that Co2Cr1-xMnxSi alloys are half-metallic within the whole studied range, such that replacement of Cr by Mn keeps the energy gap in the minority-spin band. With increasing Mn content, the total spin moment increases from 16 to 20 mu B/cell, which obeys the Slater-Pauling rule. (C) 2013 Elsevier B.V. All rights reserved.
