      abstract     = {We have investigated the magnetoelastic effects in MF(2) (M
                      = Mn, Fe, Ni) associated with the antiferromagnetic phase
                      transition temperature T(N) by neutron powder diffraction.
                      The temperature variation of the lattice parameters and the
                      unit cell volume has been determined accurately with small
                      temperature steps. From the temperature variation of the
                      lattice parameters a, c and V the lattice strains Δa, Δc
                      and ΔV associated with the antiferromagnetic phase
                      transition have been extracted. Rietveld refinement of the
                      crystal and magnetic structures from the diffraction data at
                      low temperature gave a magnetic moment of 5.12 ± 0.09
                      μ(B), 4.05 ± 0.05 μ(B) and 1.99 ± 0.05 μ(B) per Mn, Fe
                      and Ni ions, respectively. The lattice strains Δa, Δc and
                      ΔV couple linearly with the intensity of the 100 magnetic
                      reflection, which is proportional to square of the order
                      parameter of the antiferromagnetic phase transition. The
                      volume strains in MF(2) (M = Mn, Fe, Co, Ni) due to the
                      magnetostriction vary smoothly along the transition metal
                      series and seem to be correlated with the strength of the
                      exchange interaction and the moments of the magnetic ions.},
