Magnetic characteristics of NdCo2Si2 have been studied by magnetic and neutron diffraction measurements using a single crystal. Three antiferromagnetic phases were found below 32 K. A simple collinear antiferromagnetic phase is stable in the range 0-15 K where a metamagnetic process is observed. Square-wave structures with the propagation vectors K = (0, 0, 0.928) and (0, 0, 0.785) appear for 15 K < T < 24 K and 24 K < T < 32 K (= TN) , respectively.
