      abstract     = {We report the direct observation of a theoretically
                      predicted magnetic ground state in a monolayer Fe on
                      Rh(111), which is referred to as an up-up-down-down
                      (↑↑↓↓) double-row-wise antiferromagnetic spin
                      structure, using spin-polarized scanning tunneling
                      microscopy. This exotic phase, which exists in three
                      orientational domains, is revealed by experiments with
                      magnetic probe tips performed in external magnetic fields.
                      It is shown that a hitherto unconsidered
                      four-spin–three-site beyond-Heisenberg interaction
                      distinctly contributes to the spin coupling of atoms with
                      S≥1 spins. The observation of the ↑↑↓↓ order
                      substantiates the presence of higher-order, in particular,
                      three-site interactions, in thin magnetic films of itinerant
                      magnets.},
