N2 - We present the chemical pressure effect on the specific heat and magnetic susceptibility in the substituted system CePd1-xNixAl. By substitution of 10% of Ni, TN has almost disappeared. Further substitution of Ni drastically diminishes the magnetic moment and the effective number of Bohr magnetons. The entropy integrated up to 10 K is 66% for CePdAl, and it decreases to 3% of R ln 2 with increasing x. The electronic specific-heat coefficient C/T approaches 1.1 J/mol K2 for CePd0.9Ni0.1Al at low temperatures. Single crystals for x = 0.0 and 0.1 have been grown to investigate the magnetic anisotropy.
