Abstract

We have investigated the antiferromagnetic Kondo lattice compound Ce ₈Pd₂₄Ga through neutron powder diffraction and zero-field muon spin relaxation measurements. Our neutron diffraction study reveals a commensurate type-C antiferromagnetic structure below T_N = 3.6K, with the ordered state magnetic moment of ∼0.36μ_B/Ce-atom along the cubic 〈1 1 1〉 direction. The zero-field muon spin relaxation rate exhibits a sharp increase below T_N in agreement with antiferromagnetic ordering observed by the neutron diffraction study. The origin of the reduced moment ordering has been discussed in terms of the Kondo effect.
