中文摘要 | Structure and magnetic properties of the (Nd1-xErx)(3)Fe25Cr4.0(x = 0-1.0) compounds have been investigated by means of x-ray diffraction and magnetic measurements. It is found that the compounds with x = 0-0.8 crystallize in Nd-3 (Fe, Ti)(29) type structure, A2/m space group, but those with 0.8 < x <= 1.0 crystallize in a disordered Th2Ni17-type structure, P6(3)/mmc space group. Both the Curie temperature T-c and the saturation magnetization M-s of (Nd1-xErx)(3)Fe25Cr4.0 decrease monotonically with increasing Er content. The easy magnetization direction (EMD) of the Nd3Fe25Cr4.0 compound is close to the 0401 direction at room temperature, but makes a tilted angle with the basal plane of 1 :5 structure. With increasing Er content the EMD changes to much close to the [402] direction and the tilted angle increases. AC susceptibility measurement indicates the appearance of a spin reorientation at low temperatures for the compounds with x = 0-0.4 and x = 1.0, and the spin reorientation temperature T-c increases monotonically as the Er content increases for the compounds with x = 0-0.4. First-order magnetization process (FOMP) is observed in the compounds with 0 <= x <= 0.8 and the critical field B-er of the FOMP decreases with increasing Er content from 6.6T for x = 0 to 2.0T for x = 0.7. |
