Influence of hydrogenation on magnetic interactions in intermetallic RNi (R = Gd, Tb, Dy) compounds

The influence of hydrogenation on the magnetic properties of intermetallic compound RNi is reported. GdNiH3.2, TbNiH3.4, DyNiH 3.4 hydrides have been synthesized and their magnetic properties were investigated in the tempe

Magnetic properties of the intermetallic compounds RNi (R=Gd, Tb, Dy, Sm) and their hydrides

Hydrogen interaction with RNi intermetallic compounds and the influence of hydrogen on magnetic properties of these compounds were investigated. Ternary hydrides GdNiH3.2, TbNiH3.4, DyNiH3.4 and SmNiH3.7 were pr

Electronic structure and surface reconstruction of DyNi films grown on W(1 1 0)

Angle-resolved photoemission and low-energy electron diffraction (LEED) were used to study thin films of DyNi(0 0 1) grown in situ under ultra-high vacuum conditions by codeposition of Dy and Ni onto a W(1 1 0) substrate and subsequent annealing. Guided by the results of electronic structure calculations an observed (3 × 1) overstructure of the LEED pattern and the appearance of a Dy 5d-derived surface state at the Fermi energy are explained by a reconstruction of the (0 0 1) surface resulting from missing Ni rows in the topmost atomic layer. Similar to metallic Gd(0 0 0 1) the d-like behavior of the obtained surface state may influence surface magnetic properties of thin films of DyNi.

Structure and magnetic properties of RNi (R = Gd, Tb, Dy, Sm) and R 6M1.67Si3 (R = Ce, Gd, Tb; M = Ni, Co) hydrides

The paper reports the influence of hydrogen absorption on the structure and magnetic properties of intermetallic compounds RNi (R = Gd, Tb, Dy, Sm) and R6M1.67Si3 (R = Ce, Gd, Tb; M = Ni, Co). It is demonstrated that the ternary hydrides GdNiH3.2, TbNiH3.4, DyNiH3.4, and SmNiH3.7 have similar CrB-type orthorhombic structures. In the structures of TbNiD3.4 and DyNiD3.4, deuterium atoms occupy tetrahedral 8f-interstices [R3Ni], trigonal bipyramidal 4c-interstices [R3Ni2], and octahedral 4b-interstices [R4Ni2]. The hydrides of R 6M1.67Si3 retain the hexagonal structure of their parent compound. In the structures of Tb6Co 1.67Si3D11.2 and Ce6Ni 1.67Si3D12.3, deuterium atoms occupy tetrahedral 4f-interstices [R3M] and two types of tetrahedral interstices [R3Si]: 12i1 and 12i2. The formation of the hydrides causes a substantial expansion of the metallic sublattice, a weakening of ferromagnetic interactions, and a decrease in the magnetic transition temperature.

Dy-Ni-B System

Based on x-ray diffraction data, the 1070-(0-33 mol % Dy) and 870-K (33-100 mol % Dy) sections of the Dy-Ni-B phase diagram were constructed. The existence of 13 ternary borides was confirmed, and two new borides with the tentative compositions Dy2Ni2B and Dy3Ni8B9 and unidentified structures were obtained. The coordination polyhedra and configurations of boron atoms in the borides of the Dy-Ni-B system are examined. The phase relations in the systems Ln-Ni-B (Ln = yttrium group rare earth)are analyzed
