72.15.Eb - Opis:
- Study of resistivity and specific heat on $CeCo_{12}B_6$ compound was performed in a temperature range 2.5-300 K. The specific heat exhibits pronounced λ-type anomaly in the vicinity of the Curie temperature $T_C$. Using the Debye-Einstein model the following parameters were obtained: the Debye temperature $θ_D$ = 185 K, coefficient of the electron specific heat $γ_{el}$ = 115 mJ/mol K. The parabolic temperature dependence of resistivity ρ(T) = $ρ_0 + A_ρT^2$ was observed below $T_C$ in agreement with ferromagnetic state. Comparison of dρ/dT(T) with $C_M(T)$ allows to confirm their similar character, accordingly to theory of critical behavior.
