      abstract     = {Skyrmions are topologically protected field configurations
                      with particle-like properties that play an important role in
                      various fields of science. Recently, skyrmions have been
                      observed to be stabilized by an external magnetic field in
                      bulk magnets. Here, we describe a two-dimensional square
                      lattice of skyrmions on the atomic length scale as the
                      magnetic ground state of a hexagonal Fe film of
                      one-atomic-layer thickness on the Ir(111) surface. Using
                      spin-polarized scanning tunnelling microscopy we can
                      directly image this non-collinear spin texture in real space
                      on the atomic scale and demonstrate that it is
                      incommensurate to the underlying atomic lattice. With the
                      aid of first-principles calculations, we develop a spin
                      model on a discrete lattice that identifies the interplay of
                      Heisenberg exchange, the four-spin and the
                      Dzyaloshinskii-Moriya interaction as the microscopic origin
                      of this magnetic state.},
