Abstract

The magnetic susceptibility and isothermal magnetization are studied on Ce_{x - 5} La_x Ni₂ Si₃ (x = 0, 0.5, 1, 2, 3 and 4.5). The temperature of antiferromagnetic ordering due to the twelve magnetic Ce ions in two hexagons decreases with increasing x and is suppressed above x = 2. The paramagnetism which arises from frac(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.
