  Synthesis and structure determination of a new series of hydrogen storage alloys; RMg2Ni9 (R=La, Ce, Pr, Nd, Sm and Gd) built from MgNi2 Laves-type layers alternating with AB5 layers

  摘要：

  A number of new ternary magnesium based alloys, RMg2Ni9 (where R=La, Ce, Pr, Nd, Sm and Gd), have been synthesized by reacting a mixture of MgNi2 with RNi5 intermetallic compounds or by direct combination of the elements in the atomic ratio R:Mg:Ni=1:2:9. The crystal structure, determined by Guinier-Hagg X-ray powder diffraction, is related to the hexagonal PuNi3 type. All interatomic distances are close to the corresponding ones in (C-15) MgCu2, (C-14) MgZn2, (C-36) MgNi2, RNi3 and RNi5 of metallic-type bonding. (C) 1997 Elsevier Science S.A.

  Electrochemical formation of Sm–Ni alloy films in a molten LiCl–KCl–SmCl3 system

  摘要：

  The electrochemical formation of Sm-Ni alloys was investigated in a molten LiCl-KCl-SmCl3 (0.5 mol%) system at 723 K. The cyclic voltammogram for a Mo electrode showed the reduction wave from Sm(III) to Sm(II) at 1.60 V (vs Li+/Li), but no reduction wave from Sm(II) to Sm metal. For a Ni electrode, small cathodic currents were observed at potentials more negative than 0.10 V, which indicated the formation of Sm-Ni alloy. The formation of an SmNi2 phase was confirmed by XRD analysis of a sample prepared at 0.10 V for 72 h. The thickness of the SmNi2 film was estimated to be approximately 100 nm. A much thicker SmNi2 film (similar to 20 mum) was obtained by cathodic galvanostatic electrolysis at 50 mA cm(-2) in a time period as short as 1 h. Since Li metal was codepositing during the electrolysis and the SmNi2 film was rapidly formed, this electrochemical formation method was termed the 'Li codeposition method'. The formed SmNi2 film was changed to other alloy phases by anodic potentiostatic electrolysis. The formation potentials of SmNi5, SmNi3 and SmNi2 were found to be 1.20, 0.65 and 0.29 V, respectively.

  intermetallic compounds due to their single-phase characteristics and high configuration entropy. The magnetic cocktail effect is observed in magnetic measurements. These intermetallic compounds show low-temperature magnetic transition and field-induced ferromagnetic characteristics. The cocktail effect is suggested to be modulated by the spins with random directions at rare earth and transition metal sublattices

  The SmNi5 intermetallic compound has been investigated by arc-melting. Powder X-ray diffraction analysis and Rietveld refinement revealed that the sample crystallized in the hexagonal CaCu5-type structure P6/mmm space group with the following lattice parameters: a = 4.9203 (1) angstrom, c = 3.9662 (1) angstrom. These lattice parameters for the compound are in good agreement with previous theoretical result and experimental data. The EDX analysis has been performed to confirm the composition of this compound. The chemical bonding in SmNi5 was analyzed using atomic Hirshfeld surfaces, and this analysis supports the presence of the structural elements and the coordination of Sm (1a), Ni (2c) and Ni (3 g). This study indicates the different types of interatomic interactions between the Sm and Ni atoms and the weak interactions between Sm-Sm atoms were also observed along the c axis. The magnetic properties and magnetocaloric effect (MCE) have been established by the magnetization and isothermal magnetization of different temperature measurements. The magnetization curve as a function of temperature shows a magnetic transition from ferromagnetic to paramagnetic state at the Curie temperature T-C = 29 K. We have studied the MCE phenomena in the vicinity of magnetic phase transitions in terms of magnetic entropy change. The temperature dependence of the magnetization, the magnetic entropy change Delta S-M, as well as the relative cooling power around the second-order magnetic transition and the Arrott plots for the alloys are reported.
