      abstract     = {The nature of magnetic correlation at low temperature in
                      two‐dimensional artificial magnetic honeycomb lattice is a
                      strongly debated issue. While theoretical researches suggest
                      that the system will develop a novel zero entropy spin solid
                      state as T → 0 K, a confirmation to this effect in
                      artificial honeycomb lattice of connected elements is
                      lacking. This study reports on the investigation of magnetic
                      correlation in newly designed artificial permalloy honeycomb
                      lattice of ultrasmall elements, with a typical length of
                      ≈12 nm, using neutron scattering measurements and
                      temperature‐dependent micromagnetic simulations. Numerical
                      modeling of the polarized neutron reflectometry data
                      elucidates the temperature‐dependent evolution of spin
                      correlation in this system. As temperature reduces to ≈7
                      K, the system tends to develop novel spin solid state,
                      manifested by the alternating distribution of magnetic
                      vortex loops of opposite chiralities. Experimental results
                      are complemented by temperature‐dependent micromagnetic
                      simulations that confirm the dominance of spin solid state
                      over local magnetic charge ordered state in the artificial
                      honeycomb lattice with connected elements. These results
                      enable a direct investigation of novel spin solid
                      correlation in the connected honeycomb geometry of 2D
                      artificial structure.},
