✦ Synopsis

Specific heat measurements

on Ce,SB, were carried out in various magnetic fields and the phase diagram was determined.

A large linear specific heat coefficient y = 160 mJ/K2 mol Ce was obtained at H = 0. The entropy at the phase transition temperature was only 40% of In2 and largely suppressed by applied magnetic field. Similarity between Ce,Bi, and Ce,Sb, was found. Various anomalous properties suggest competition between Kondo and ferromagnetic interactions in both compounds.
