| 中文摘要 | Static magnetic order of quasi-two-dimensional FeAs compounds Sr(4)A(2)O(6-x)Fe(2)As(2), with A = Sc and V, has been detected by Fe-57 Mossbauer and muon spin relaxation (mu SR) spectroscopies. The nonsuperconducting stoichiometric (x = 0) A = Sc system exhibits a static internal/hyperfine magnetic field both at the Fe-57 and mu(+) sites, indicating antiferromagnetic order of Fe moments below T-N = 35 K with similar to 0.1 bohr magneton per Fe at T = 2 K. The superconducting and oxygen deficient (x = 0.4) A = V system exhibits a static internal field only at the mu(+) site below T-N similar to 40 K, indicating static magnetic order of V moments coexisting with superconductivity without freezing of Fe moments. These results suggest that the 42622 FeAs systems belong to the same paradigm with the 1111 and 122 FeAs systems with respect to magnetic behavior of Fe moments. |
