The structures and stabilities of Fe6-xNix (x=0-5) clusters have been systematically studied at the BPW91 level in density functional theory. Theoretical results show that the doping of Ni atoms do not change the rectangular bipyramid of Fe6 cluster, and structural features are determined by the ratio between the number of Ni atoms and Fe atoms. When the number of Ni atoms is less than 3, Fe6-xNix clusters have the similar high stability as Fe6. However, the stabilities of cluster decrease when the number of Ni atoms is equal or larger than 3..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
