Abstract

New intermetallic magnesium compounds RE2Ni2Mg 3 (RE = Gd, Dy-Tm, Lu) were synthesized from the elements by induction melting. They are isotypic with Tb2Ni2Mg 3. The structure of Gd2Ni2Mg3 was refined from X-ray powder data: Cmmm, a = 398.7(1), b = 2121.9(7), c = 368.39(9) pm, RB = 7.49%, 3800 data points, 23 parameters. The RE 2Ni2Mg3 intermetallics are intergrowth variants of AlB2- and CsCl-related slabs. Gd2Ni2Mg 3 is a Curie-Weiss paramagnet above 75 K with an experimental magnetic moment of μeff = 8.16(1) μB /Gd atom. Antiferromagnetic ordering sets in at TN = 42.0(5) K.
