This member of the pnictide family shows a broad variety of magnetic and superconducting features. Especially the interplay of the Eu and Fe magnetic sublattices in combination with various Co content require detailed studies with single crystal neutron diffraction. Using the short wavelengths of HEiDi to overcome the strong Eu neutron absorption in these compounds HEiDi was able to contribute significant information to various studies on this family of compounds.
