Abstract: Muon spin relaxation MuSR measurements in iron oxy-pnictide systems haverevealed: 1 commensurate long-range order in undoped LaOFeAs; 2 Besselfunction line shape in LaO0.97F0.03FeAs which indicates possibleincommensurate or stripe magnetism; 3 anomalous weak magnetism existing insuperconducting LaOFeP, CeO0.84F0.16FeAs, and NdO0.88F0.12FeAs but absentin superconducting LaO0.92F0.08FeAs; and 4 scaling of superfluid densityand Tc in the Ce, La, and Nd-FeAs superconductors following a nearly linearrelationship found in cuprates.
