Warning! Note that elemental potentials taken from alloy descriptions may not work well for the pure species. This is particularly true if the elements were fit for compounds instead of being optimized separately. As with all interatomic potentials, please check to make sure that the performance is adequate for your problem.

Updated! Potentials that share interactions are now listed as related models.

Abstract: We present the derivation of an interatomic potential for the iron–phosphorus system based primarily on ab initio data. Transferability in this system is extremely problematic, and the potential is intended specifically to address the problem of radiation damage and point defects in iron containing low concentrations of phosphorus atoms. Some preliminary molecular dynamics calculations show that P strongly affects point defect migration.

Notes: The file fep4.19 was obtained from
http://homepages.ed.ac.uk/graeme/moldy/moldy.html and posted with the permission of G.J. Ackland. Besides the parameterized functions in the file, there are also some calculated quantities useful as confirmation.
From that website: "The iron potential here is slightly improved from the 2003 version to eliminate negative thermal expansion. It has a melting point of 1796 K."
