To clarify anomalous behaviour under high pressure in the antiferromagnet EuPt₂ Si₂(T_N = 15 K), effects of substitution of Ni for Pt in EuPt₂ Si₂ are investigated. Eu(Pt_{1 - x} Ni_x)₂ Si₂ is of single phase in the concentration range of 0 ≤ x ≤ 0.25 with preserving the identical crystal structure. The Ni-substitution decreases the lattice volume and the Néel temperature T_N. For x ≥ 0.20 the antiferromagnetism is collapsed completely. These phenomena correspond well to the behaviour under high pressure in EuPt₂ Si₂ and are associated with Eu valence variation toward a nonmagnetic trivalent direction.
