EAM potential to describe FeNi in the complete concentration range. The main focus was put on the description of experimentally observed intermetallic phases and point defect properties in a dilute Fe-rich matrix. The Fe and Ni potentials were taken from [Mendelev et al., Philos. Mag. 83 (2003) 3977] and [Voter and Chen, Mater. Res. Soc. Symp. Proc. 82 (1987) 175], respectively.
