      abstract     = {We demonstrate a canted magnetization of biatomic zigzag Co
                      chains grown on the (5 × 1) reconstructed Ir(001) surface
                      using density functional theory (DFT) calculations and
                      spin-polarized scanning tunneling microscopy (SP-STM)
                      experiments. It is observed by STM that biatomic Co chains
                      grow in three different structural configurations. Our DFT
                      calculations show that they are all in a ferromagnetic (FM)
                      state. Two chain types possess high symmetry due to two
                      equivalent atomic strands and an easy magnetization
                      direction that is along one of the principal
                      crystallographic axes. The easy magnetization axis of the
                      zigzag Co chains is canted away from the surface normal by
                      an angle of 33°. This giant effect is caused by the broken
                      chain symmetry on the substrate in combination with the
                      strong spin–orbit coupling of Ir. SP-STM measurements
                      confirm the stable FM order of the zigzag chains with a
                      canted magnetization},
