Possible Fe/Cu ordering schemes in the 2a superstructure

Based on magnetic structure and TEM studies of bornite we propose a new 2 a Fe/Cu ordered superstructure model with symmetry F 43 m and formula Cu8Fe4S8 First principles calculations (LAPW implemented in WIEN97 code) of two Fe/Cu ordering schemes indicate that at the ground state the Fe atoms should fill the tetrahedral sites of sulfur atoms in the anti-fluorite cube and the vacancies are
