EN

The magnetic properties and magnetocaloric effect (MCE) in DyNi_{4}Si have been studied by the magnetization and specific heat measurements. The saturation magnetic moment in μ_{0}H=9 T is equal to 7.9 μ_{B}/f.u at 4.2 K. A significant MCE has been observed around the second order phase transition at T_{C}=11 K. The maximum magnetic entropy change is -Δ S_{M}=14.5 J kg^{-1}K^{-1} for the magnetic field change of 9 T.
