| The results of new magnetic dc and neutron diffraction measurements of DyCoSi2 compound are presented. Below TN equal to 10.9 K the Dy moments form collinear G-type structure with the moment parallel to the c-axis. The value of Dy-moment equal to 5.5(2) μB are smaller than free Dy3+ ion value (10.0 μB). These and the three-step magnetization process indicate the strong influence of the crystal electric field on the stability of the magnetic order. Increase of the values of the lattice parameters at 1.5 K in reference of these at 20 K indicate magnetostriction effect at low temperatures. |
