  Hydrogen-induced phase transitions of GdZnMg compounds

  摘要：

  Compounds of the composition GdZn1-xMgx are pseudo-binary compounds with a B2-(CsCl-type)-like structure. The compounds are ferromagnets with Curie temperatures between 117 K (x = 1) and 268 K (x = 0). By hydriding, the structural as well as the magnetic properties of these compounds change drastically, a maximum hydrogen uptake of about 2 H atoms per formula unit being achieved. The hydrides with the composition GdZn1-xMgxH-2 were found to be paramagnetic at temperatures above 5 K. They revealed X-ray diffraction patterns which were similar to the pattern of GdH2 (CaF2-type). By reducing the hydrogen concentration using thermal desorption, a ferromagnetic hydride phase with a Curie temperature of about 50 K was obtained for the Zn-rich compounds. By complete H desorption, the original Zn-rich compounds are formed again, whereas GdMg can not be re-formed due to the evaporation of Mg. The hydride phases could be identified by their characteristic magnetic and structural properties, which in the case of GdZn proved to be independent of the H isotope used in the hydrogenation process.

  Gd+GdZn biphasic magnetic composites synthesized in a single preparation step: Increasing refrigerant capacity without decreasing magnetic entropy change

  摘要：

  Biphasic Gd + GdZn composites (Gd(50+x)Zn(50-x); x = 0, 5, 15 and 25 at.%) were successfully obtained in a single fabrication step by induction melting. X-ray microdiffraction results reveal the homogeneity of all the prepared samples and indicate a combination of GdZn and Gd phases with different proportions. With this method, the main drawbacks of preparing composites have been avoided, providing the additional advantage of enhanced thermal conductivity between phases. The biphasic Gd + GdZn composite shows an enhanced refrigerant capacity in comparison to Gd (11%) as well as to single phase GdZn (45%). Heat capacity measurements provide an adiabatic temperature change of around 3.5 K for 20 kOe for the optimal composite. (C) 2016 Elsevier B.V. All rights reserved.

  Phase equilibria in the R-rich regions of the R-Cu and R-Zn binary systems (R=Pr and Gd) have been investigated by differential thermal analysis, X-ray powder diffractometry, metallographic analysis and quantitative electron probe microanalysis. In these regions, the lowering (DeltaT) of the melting and transformation temperatures of the rare earth metals by addition of copper and zinc resulted in eutectic and catatectic or eutectoidal type reactions. The DeltaT observed in these systems are discussed and compared with those reported in the literature for the binary systems of Pr and Gd with Mg and with the elements from the 9th to the 14th group of the Periodic Table. In order to complete this systematics, a few Pr-rich Pr-Cd alloys have also been prepared and analysed. (C) 2001 Elsevier Science B.V. All rights reserved.
