| 中文摘要 | Polycrystalline Nd(Mn1-xFex)(2)Ge-2 (0 <= x <= 1) compounds have been prepared by arc-melting. X-ray powder diffraction analysis shows that all samples crystallize in the ThCr2Si2-type structure with the space group 14/mmm. The substitution of Fe for Mn results in decreases of the lattice constants a, c and the unit-cell volume V. Magnetic properties and magnetocaloric effect of the compounds Nd(Mn0.9Fe0.1)(2)Ge-2 and Nd(Mn0.8Fe0.2)(2)Ge-2 have been studied by magnetic measurements. A spin reorientation transition at about 188 K is observed for Nd(Mn0.9Fe0.1)(2)Ge-2. The Nd(Mn0.8Fe0.2)(2)Ge-2 compound shows more complicated magnetic behavior, which is characterized by four magnetic ordering states below room temperature. The maximum values of the magnetic entropy change are 2.35 and 1.84 J kg(-1) K-1 for x = 0.1 and 0.2, respectively, under the applied field changing from 0 to 5T. The relative cooling powers of Nd(Mn0.9Fe0.1)(2)Ge-2 and Nd(Mn0.8Fe0.2)(2)Ge-2 are 145.9 and 133.8 J kg(-1) under an applied field change of 5T. (C) 2009 Elsevier B.V. All rights reserved. |
