Abstract

A series of REMgNi4 (RE = La, Ce, Pr, Nd, Y), La1−xNdxMgNi4 (x = 0.1–1.0) and LaMgNi4−y (y = 0.1–0.4) compounds have been prepared and characterized via X-ray diffraction (XRD). The lattice constant (a) and cell volume (V) of the REMgNi4 phase in these compounds were calculated with Si as the internal standard at 298 K. These results indicate that an apparent translation from the LaMgNi4 phase to the NdMgNi4 phase was observed with an increase of x from 0.1 to 1.0 in single-phase La1−xNdxMgNi4 compounds, while non-stoichiometric LaMgNi4−y (y = 0.1–0.4) compounds maintain their original single-phase structure, though the increase of the lattice constant (a) of the LaMgNi4 phase has been observed with an increase of y.
