The magnetic susceptibility and isothermal magnetization are studied on Cex-5LaxNi2Si3 (x = 0, 0.5, 1, 2, 3 and 4.5). The temperature of antiferromagnetic ordering due to the twelve magnetic Cc ions in two hexagons decreases with increasing x and is suppressed above X = 2. The paramagnetism which arises from 2/20 of the spins lying inside the hexagonal is observed below T-N in X <= 1. The signature of spin fluctuation is also observed in magnetization curves. The spin fluctuation is suppressed as the magnetic field exceeds the metamagnetic transition field. (c) 2007 Elsevier B.V. All rights reserved.
