摘要：For the small rhenium boride clusters, we carried out detailed calculations based on density-functional theory. The results indicate that the ratio of boron to rhenium with 2:1 and 4:3 possess higher stability among considered Rem Bn (m = 1 - 3, n = 1 - 3 m) clusters, which the ratio with 2:1 was also found in the corresponding bulk phase. In addition, we also investigated the magnetic moment of Rem Bn clusters. The results show that the magnetic moment of Re2 B6 cluster is as high as 4 μB. Furthermore, the origin of the magnetic moment is analyzed and discussed. ? 2008 Elsevier B.V. All rights reserved.
