中文摘要	By measuring the magnetization hysteresis loops of superconducting Ba(0.6)K(0.4)Fe(2)As(2) single crystals, we obtained the high upper critical field and large current carrying ability, which point to optimistic applications. The fishtail (or second peak) effect is also found in the material, and the position of the vortex pinning force shows a maximum at 1/3 of the reduced field, being consistent with the picture of vortex pinning by small size normal cores in the sample. Together with the resistive measurements, for the first time the vortex phase diagram is obtained for superconductor Ba(0.6)K(0.4)Fe(2)As(2). (C) 2008 American Institute of Physics.
