The magnetic field dependence of the specific heat was examined for CeFe2 and Ce(Fe0.9Co0.1)2. The former compound is a simple ferromagnet, while the latter shows an antiferromagnetic-to-ferromagnetic (AF-to-F) transition with increasing temperature and undergoes a metamagnetic transition at around 6 T at low temperatures. The results indicate that the electronic specific heat coefficient, γ, is larger in the F state than in the AF state. These results suggest the importance of the electronic specific heat as regards the entropy change associated with the AF-to-F transition. In the F state, a decrease of γ with increasing field was observed for Ce(Fe0.9Co0.1)2 as well as for CeFe2. The origin of this behaviour is also discussed.
