(Color online) Temperature dependence of the electrical resistivity for SmFeAsO0.75. The solid line is the linear fitting of the resistivity. The inset is the resistivity broadening of SmFeAsO0.75 with increasing magnetic field up to 9 T.
(Color online) Temperature dependence of specific heat at zero field. The solid line is the fitting curve of the normal state specific heat by combined Einstein–Debye model. The lower inset shows the enlarged part of superconducting transition of the specific heat plotted as C/T versus T. The upper inset is the enlarged low temperature specific heat peak at the field of 0 T and 9 T.
(Color online) The temperature dependence of specific heat at low temperatures for 0 T and 9 T plotted as C/T versus T2 . The solid lines are the linear fits between 14 and 28 K.
(Color online) Temperature dependence of the specific heat close to Tc in 0 T and 9 T plotted as C/T versus T. The inset shows [C(0T) − C(9T)]/T versus temperature.
(Color online) Temperature dependence of the Hall coefficient RH . The inset shows a good linear relationship between ρxy and H at different temperatures.
