中文摘要	Structure and magnetic properties of (Nd1-xYx)(3)Fe29-yCry compounds with x = 0-1.0 and y = 4-1.5 have been investigated. It is found that in an adequate annealing temperature range all the investigated compounds crystallize in the Nd-3(Fe,Ti)(29)-type structure. However when the annealing temperature is below 1323 K, the Y3Fe27.5Cr1.5 compound crystallizes in a disordered CaCu5-type structure. Substitution of Y for Nd leads to a reduction of the lattice parameters. The Curie temperature T-c shows no clear change as the Y and Cr contents change in the above-mentioned concentration region. With increasing Y content, the easy magnetization direction changes from close to the [0 4 0] direction to the [40-2] direction. The X-ray-diffraction patterns and the AC susceptibility of the (Nd1-xYx)(3)Fe29-yCry samples reveal a spin reorientation phenomenon for x = 0-0.4 as the temperature decreases from room temperature to 77 K. The spin reorientation temperature T-sr increases monotonically with increasing Y content from 158 K for x = 0 to 201 K for x = 0.4. (c) 2005 Elsevier B.V. All rights reserved.
