Abstract

Specific heat measurements on Ce₄Bi₃ at low temperature were carried out in various magnetic fields, and the phase diagram with dH_c/dT > 0 was determined. A large linear specific heat coefficient, γ = 200 mJ/K²mol Ce was obtained at H = 0. The entropy at the phase transition temperature is only 40% of ln 2. The ordered anisotropy in magnetization cannot be explained by a simple crystalline field model. Various anomalous properties suggest competition between the Kondo and ferromagnetic interaction in Ce₄Bi₃.
