Abstract

The thermal property has been studied on Ce_{1 - x} Gd_x CoSi₃, where an antiferromagnetic ordering is observed. T_N linearly decreases with x and is suppressed at x = 0.2. The non-Fermi-liquid behavior in C / T is found at x = 0.2. Another anomaly is found at 3 K at x > 0.2. C / T is very large below 3 K and diverges at x = 0.4. The - ln T behavior in C / T is also observed at x = 0.4. This indicates that new quantum critical point exists in x = 0.4.
