Resumen en inglés

Extending our study on the characterisation of the magnetic properties of the ternary germanides based on cerium and nickel, we have performed magnetisation measurements and neutron powder diffraction on CeNiGe3. The antiferromagnetic structure of this compound is dependent on temperature: (i) for T between TN=5.9(2) and 5.0(2) K, the magnetic peaks are associated with the k 1=(1 0 0) propagation vector; (ii) below 5.0(2) K, the two propagation vectors k 1=(1 0 0) and k 2=(0 0.409(1) 1/2) coexist, but the intensities of the magnetic peaks corresponding to k 1 decrease with temperature below 4.1(2) K. We discuss this complex magnetic behaviour in relation to the magnetic structure reported for Ce3Ni2Ge7.< Leer menos
