Magnetism, structure, thermodynamics and transport of RO1-xFxFeAs (R=La, Ce, Sm, Gd) superconductors
We discuss magnetism, structure, thermodynamics and transport properties of the new oxypnictide superconductors RO1-xFxFeAs (R=La, Ce, Sm, Gd). At zero fluorine doping we observe a close link between electronic, structural and magnetic degrees of freedom at the structural and the magnetic phase transitions TS 160K and TN 138 K. F-doping leads to the suppression of these transitions and the emergence of superconductivity. The superconducting doping levels exhibits an interesting interplay between magnetism and superconductivity. We discuss the influence of different R-ions on the physical properties.
