Description
Summary:The evolution of magnetism in the DyNi1−xCuxAl pseudoternary series was studied. The results of magnetization, magnetic susceptibility, heat capacity and neutron diffraction experiments are summarized and discussed in context of other RNi1−xCuxAl pseudoternaries. The compounds with x ≤ 0.2 adopt the coexistence of antiferromagnetic and ferromagnetic order similar to that one in the parent DyNiAl. The compounds with 0.3 ≤x ≤ 0.6 exhibit antiferromagnetic order only while the compounds with x ≥ 0.9 are ferromagnets. The compounds with 0.6 ≤x ≤ 0.9 exhibit signs of short-range correlations, especially the compound with x = 0.8 does not show any long-range magnetic order at all. It is in accordance with previously studied series.
