Abstrakt: A magnetic order in orthorhombic GdCu2 was investigated via a single crystal neutron diffraction with thermal neutron. Magnetic peaks were observed at incommensurate positions described by the ordering vector q = (δ, 1, 0) with δ = 0.678 at 4.6 K. This ordering vector is close to the commensurate one with qc = (2/3, 1, 0) reported earlier, but clearly deviates. The incommensurate nature of the magnetic order in GdCu2 is further corroborated by the peak shift with temperature below TN. [ABSTRACT FROM AUTHOR]
