Résumé en anglais
In the light of numerous magnetic data obtained on the ternary compounds R2T2X (R=U, Ce; T=Ni, Rh, Pd and X=Sn, In), which crystallize in the tetragonal U2Fe2Sn-type structure (P4/mbm space group) but exhibit various ...Lire la suite >
In the light of numerous magnetic data obtained on the ternary compounds R2T2X (R=U, Ce; T=Ni, Rh, Pd and X=Sn, In), which crystallize in the tetragonal U2Fe2Sn-type structure (P4/mbm space group) but exhibit various magnetic structures, we demonstrate the efficiency of a Ruderman-Kittel-Kasuya-Yosida model based on a non-spherical Fermi surface to account for the magnetic interactions involved in these systems. Considering as magnetic ground states the basis vectors of the irreducible representations associated to P4/mbm space group, (4h) Wyckoff position [crystallographic site for Ce or U] and...< Réduire
