      abstract     = {The magnetic structures adopted by the Fe and Sm
                      sublattices in SmFeAsO have been investigated using
                      element-specific x-ray resonant and nonresonant magnetic
                      scattering techniques. Between 110 and 5 K, the Sm and Fe
                      moments are aligned along the c and a directions,
                      respectively, according to the same magnetic representation
                      Gamma(5) and the same propagation vector (1 0 1/2). Below 5
                      K, the magnetic order of both sublattices changes to a
                      different magnetic structure, and the Sm moments reorder in
                      a magnetic unit cell equal to the chemical unit cell.
                      Modeling of the temperature dependence for the Sm
                      sublattice, as well as a change in the magnetic structure
                      below 5 K, provides clear evidence of a surprisingly strong
                      coupling between the two sublattices, and indicates the need
                      to include anisotropic exchange interactions in models of
                      SmFeAsO and related compounds.},
