The pseudogap state is one of the peculiarities of the cuprate high-temperature superconductors. Here we investigate its presence in BaCoxFe2-xAs2, a member of the pnictide family, with temperature-dependent scanning tunneling spectroscopy. We observe that for under, optimally and overdoped systems the gap in the tunneling spectra always closes at the bulk T-c, ruling out the presence of a pseudogap state. Copyright (C) EPLA, 2010
