Abstract

Specific heat measurements on Ce ₄ SB ₃ were carried out in various magnetic fields and the phase diagram was determined. A large linear specific heat coefficient γ = 160 mJ{plus 45 degree rule}K ² mol Ce was obtained at H = 0. The entropy at the phase transition temperature was only 40% of ln2 and largely suppressed by applied magnetic field. Similarity between Ce ₄ Bi ₃ and Ce ₄ Sb ₃ was found. Various anomalous properties suggest competition between Kondo and ferromagnetic interactions in both compounds.
