Résumé / Abstract

The structure and magnetic properties of Nd_1-xHo_xMn₂Ce₂ (0.0≤x≤ 1.0) germanides were studied by X-ay diffraction (XRD), differential scanning calorimetry (DSC) techniques and AC magnetic susceptibility measurements. All compounds crystal ize in the ThCr₂Si₂-type structure with the space group 14/mmm. Substitution of Ho for Nd leads to a linear decrease in the lattice constants md the unit cell volume, and the magnetic interactions in the Mn sublattice cross over from a ferromagnetic character to an antiferromagnet c one. A typical SniMn₂Ge₂-like behavior is observed for x=0.6 and 0.8. The results are collected in a phase diagram.
