Unconventional electronic reconstruction in undoped across the spin density wave transition
Abstract
Through a systematic high-resolution angle-resolved photoemission study of the iron pnictide compounds , we show that the electronic structures of these compounds are significantly reconstructed across the spin density wave transition, which cannot be described by a simple folding scenario of conventional density wave ordering. Furthermore, we find that LDA calculations with an incorporated suppressed magnetic moment of 0.5μB can match well the details in the reconstructed electronic structure, suggesting that the nature of magnetism in the pnictides is more migratory than local, while the origin of suppressed magnetic moment remains an important issue for future investigations.
