The Mg-Rich Phase NdNiMg: Structural and Magnetic Properties.

The intermetallic NdNiMg is the Mg-richest phase (more than 88 atom % of Mg) discovered in the Mg-Nd-Ni system. Its structure was determined by X-ray diffraction on single crystal with the following crystal data: tetragonal system, P4/ nmm, Z = 2, a = 10.0602(1) Å, c = 7.

NdNiMg5, a new magnesium-rich phase with an unusual structural type.

The new intermetallic NdNiMg5 was discovered during the study of the Mg-rich part of the Mg-Nd-Ni system. It was synthetized by melting of the constituent elements in a sealed tantalum tube with subsequent annealing. Its structure was determined by X-ray diffraction on a single crystal.
