Description
Structure and magnetic properties of (Nd1-xYx)3Fe29-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 Nd3(Fe,Ti)29-type structure. However when the annealing temperature is below 1323K, 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 Tc 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 [040] direction to the [40-2] direction. The X-ray-diffraction patterns and the AC susceptibility of the (Nd1-xYx)3Fe29-yCry samples reveal a spin reorientation phenomenon for x=0-0.4 as the temperature decreases from room temperature to 77K. The spin reorientation temperature Tsr increases monotonically with increasing Y content from 158K for x=0 to 201K for x=0.4
