- The magnetic specific heat of GdNi$\text{}_{2}$Sn$\text{}_{2}$, GdNi$\text{}_{2}$Sb$\text{}_{2}$ and GdCu$\text{}_{2}$Sb$\text{}_{2}$ shows a λ-type anomaly at T$\text{}_{N}$ 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$\text{}_{N}$. Above T$\text{}_{N}$ 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$\text{}_{2}$Sn$\text{}_{2}$ the propagation vector Q=(0.3,1/2,1/2) was found with the magnetic moments along the [1,0,0] axis.
