Abstract

We successfully synthesized a new ferromagnetic Ce-compound, CeAgAl₃ (T_C = 3.0 K). From susceptibility measurement using the aliened crystal, effective Bohr magneton, μ_eff, and Weiss temperature, θ, were estimated to be about 2.23 μ_B and 10.1 K along ab-plane, respectively, indicating the tri-valent state for Ce and weak ferromagnetic interaction between Ce ions. In M-H curve, the magnetization along the ab-plane and the c-axis up to 5 T at 1.8 K exhibited ferromagnetic behaviour saturating over 0.2 T with small magnetic hysteresis and reached the values of about 1.07 μ_B and 0.75 μ_B, respectively. These values are somewhat smaller than the theoretical value for the saturated moment of free Ce³⁺ ion (μ_s = gJ = 2.14 μ_B).
