Static magnetic order of Sr4A2O6Fe2As2 (A = Sc and V) revealed by Mössbauer and muon spin relaxation spectroscopies
Abstract
Static magnetic order of quasi-two-dimensional FeAs compounds Sr4A2O6-xFe2As2, with A= Sc and V, has been detected by Fe57 Mössbauer and muon spin relaxation (μSR) spectroscopies. The nonsuperconducting stoichiometric (x=0) A= Sc system exhibits a static internal/hyperfine magnetic field both at the Fe57 and μ+ sites, indicating antiferromagnetic order of Fe moments below TN = 35 K with ~0.1 bohr magneton per Fe at T= 2 K. The superconducting …
