摘要：

Structural and magnetic properties of the (Nd1-xHox)(3)Fe27.31Ti1.69 compounds have been investigated by means of X-ray diffraction and magnetic measurements. All the compounds with xless than or equal to0.6 crystallize in the Nd-3(Fe,Ti)(29)-type structure. Substitution of Ho for Nd leads to a contraction of the unit-cell volume and a monotonic decrease of the saturation moments M-s at 5 K. As the temperature decreases from room temperature to 5 K, a spin reorientation from easy plane to the easy cone occurs for all (Nd1-xHox)(3)Fe27.31Ti1.69 compounds investigated. It has been found that the Curie temperature T-c of the (Nd1-xHox)(3)Fe27.31Ti1.69 compound almost has a constant value, whereas the spin reorientation temperature, T-sr, decreases with increasing x. The anisotropy fields, B-a, at room temperature for the (Nd1-xHox)(3)Fe27.31Ti1.69 compounds have been determined by the singular point detection method and are found to be almost independent of the Ho content. A tentative spin phase diagram has been constructed for the (Nd1-xHox)(3)Fe27.31Ti1.69 compounds. (C) 2002 Elsevier Science B.V. All rights reserved.
