      abstract     = {An experimental study of long‐range magnetic order
                      formation mechanisms in a layered structure with a honeycomb
                      arrangement of the magnetic atoms Na2Ni2TeO6 is conducted.
                      For the first time, the strong spin correlations are
                      directly observed above the Neel temperature T N that is
                      manifested in the presence of broad diffuse peaks on neutron
                      diffraction patterns obtained with the XYZ polarization
                      analysis. Due to the possibility of separating the magnetic,
                      nuclear incoherent, and nuclear coherent contributions to
                      the total neutron scattering cross section, it is
                      unequivocally established that the observed diffuse
                      scattering has magnetic nature. The spin‐pair correlation
                      function is reconstructed by modeling diffuse neutron
                      scattering on Na2Ni2TeO6 with reverse Monte Carlo method.
                      The obtained results indicate 2D nature of the magnetic
                      correlations, and moreover, the symmetry of short‐range
                      magnetic state corresponds to long‐range zigzag‐type
                      magnetic order in the honeycomb net, which is established
                      earlier based on the theoretical calculations.},
