本文研究了均匀沉淀Co1-YNiY(OH)2(X=1.3Y)前驱体制备的Co3-xNiXO4(CNO)(0≤X≤(1.28))粉末样品的晶体结构和磁性。X射线衍射分析表明，当0：≤X≤=1.28时，样品具有立方尖晶石结构。随着镍含量(X)的增加，单位公式单位MS在5℃时的饱和磁化强度从0μBATX=0增加到0.97μBATX=90.74，随后又下降到0.78μBATX=11.28。当≥为0.23时，磁转变温度从35K ATX=00.23增加到290K ATX=11.28。根据5℃下测量的晶格参数和饱和磁化强度数据MS-Exp估算了阳离子在晶体中的分布，估算的饱和磁化强度MS-Fit的成分依赖关系与观测到的趋势一致。
The crystal structure and magnetic properties of Co3-XNiXO4(CNO) (0 ≤X≤ 1.28) powder samples produced from uniformly precipitated Co1-YNiY(OH)2(X= 3Y) precursors were investigated herein. The X-ray diffraction analysis of the samples showed that they had a cubic spinel structure when 0 ≤X≤ 1.28. With increasing nickel content (X), the saturation magnetization per formula unitMSat 5 K increased from 0 μBatX= 0 to 0.97 μBatX= 0.74, and subsequently decreased to 0.78 μBatX= 1.28. WhenX≥ 0.23, the magnetic transition temperature increased from 35 K atX= 0.23 to 290 K atX= 1.28. The distribution of the cations in the crystal was estimated from the lattice parameters and saturation magnetization data, MS-Exp, measured at 5 K. The estimated compositional dependence of the saturation magnetizationMS-Fitwas consistent with the observed trend in theMS-Exp.
