Pressure dependence of ρ near the superconducting transition for the PrFeAsO0.60F0.12 sample for: (a) pressure up to 1.3 GPa to show the increase of T c and (b) above 1.3 GPa to show the decrease of T c . Pressure dependence of (c) the different superconducting transition temperatures (\({T}_{c}^{on}\), \({T}_{c}^{m}\) and \({T}_{c}^{zero}\)) estimated using the criteria as described in the text and (d) the width of the superconducting transition ΔT c = \({T}_{c}^{on}\) − \({T}_{c}^{zero}\).
