The magnetic specific heat of GdNi_{2}Sn_{2}, GdNi_{2}Sb_{2} and GdCu_{2}Sb_{2} shows a λ-type anomaly at T_{N} with a noticeable reduction of the discontinuity compared to that expected for a simple antiferromagnet. It can be associated with the existence of amplitude modulated magnetic structure just below T_{N}. Above T_{N} a weak magnetic contribution is observed, evidencing the short-range ordering. From neutron diffraction studies it can be also concluded that investigated compounds have not simple antiferromagnetic structures. For GdNi_{2}Sn_{2} the propagation vector Q=(0.3,1/2,1/2) was found with the magnetic moments along the [1,0,0] axis.
