Abstract

We report on structure investigation and magnetization study of UNi_1-xRh_xAl solid solutions between an antiferromagnet UNiAl and a ferromagnet URhAl. The ZrNiAl-type hexagonal crystal structure of the parent compounds is preserved in the whole concentration range. Magnetization was measured as a function of magnetic field, temperature and external hydrostatic pressure. The observed complex evolution of magnetic phenomena with Rh substitution for Ni is discussed in terms of effects of the varying 5f-ligand hybridization. A tentative magnetic phase diagram is proposed.
