中文摘要	By muon spin-relaxation measurements on single-crystal specimens, we show that superconductivity in the AFe(2)As(2) (A=Ca,Ba,Sr) systems, in both the cases of composition and pressure tunings, coexists with a strong static magnetic order in a partial volume fraction. The superfluid response from the remaining paramagnetic volume fraction of (Ba0.5K0.5)Fe2As2 exhibits a nearly linear variation in T at low temperatures, suggesting an anisotropic energy gap with line nodes and/or multigap effects. .
