      abstract     = {Magnetic and structural properties of high quality
                      magnetocaloric MnFe4Si3 single crystals are investigated
                      macroscopically and on an atomic scale. Refinements of
                      combined neutron and X-ray single crystal diffraction data
                      introduce a new structural model in space group P6
                      characterized by partial ordering of Mn and Fe into layers
                      perpendicular to c on one of the transition metal sites. A
                      second transition metal site is exclusively occupied by
                      iron. MnFe4Si3 has a phase transition to a ferromagnetically
                      ordered phase at approximately 300 K and displays a strong
                      anisotropy of the magnetization and the magnetocaloric
                      effect with the easy axis of magnetization in the a,b-plane.
                      This is confirmed by a refinement of the magnetic structure
                      in the magnetic spacegroup Pm′, which shows that the spins
                      on the sites with mixed occupancy of Mn and Fe are aligned
                      in the a,b-plane. A significant magnetic moment for the site
                      exclusively occupied by iron could not be refined. The
                      thermal evolution of the lattice parameters exhibits an
                      anisotropic behavior and clearly reflects the onset of
                      magnetic ordering. A comparison of the ordered moment and
                      the effective paramagnetic moment hints toward itinerant
                      magnetism in the system.},
