| 中文摘要 | A series of layered (Sr(1-x)K(x))Fe(2)As(2) compounds with nominal x = 0-0.40 are synthesized by solid state reaction method. Similar to other parent compounds of iron- based pnictide superconductors, pure SrFe(2)As(2) shows a strong resistivity anomaly near 210 K, which was ascribed to the spin-density-wave instability. The anomaly temperature is much higher than those observed in LaOFeAs and BaFe(2)As(2), the two prototype parent compounds with ZrCuSiAs- and ThCr(2)Si(2)- type structures. K-doping strongly suppresses this anomaly and induces superconductivity. Like in the case of K-doped BaFe2As2, sharp superconducting transitions at T(c) similar to 38K is observed. We perform the Hall coefficient measurement, and confirm that the dominant carriers are hole-type. The carrier density is enhanced by a factor of 3 in comparison to F-doped LaOFeAs superconductor. |
