Abstract

We have measured the magnetic susceptibility and resistivity of Ce_{1 - x} Gd_x CoSi₃. The antiferromagnetism in GdCoSi₃ is ultimately suppressed around x = 0.4 by the enhanced Kondo effect. Non-Fermi-liquid behavior in resistivity has been observed around critical concentration. CeCoSi₃ has a complex magnetic structure in low temperature.
