N2 - We have measured temperature dependence of electrical resistivity ρ of Eu (Pt1 - x Nix)2 Si2 (0 ≤ x ≤ 0.25) to investigate the behavior associated with collapse of antiferromagnetism which was previously found in the magnetic susceptibility. For x ≤ 0.15, the antiferromagnetism survives but is gradually collapsed with increasing x. For x = 0.20 and 0.25, the ρ (T) curve exhibits T2 dependence corresponding to Fermi-liquid behavior. The T2 coefficient of the resistive A and Sommerfeld coefficient γ fulfill new grand Kadowaki-Woods relation, which implies that the samples of x = 0.20 and 0.25 are a member of heavy fermion systems.
