摘要：

Electronic-structure calculations show that the magnetic interactions between atoms in Fe have strong nonpairwise dependence. The nearest-neighbour coupling, J1, dominates and is much weaker for small perturbations around the ferromagnetic state than in the opposite limit of a disordered local moment configuration. This is consistent with substantial short-range order above T(c).
