采用溶剂热辅助多元醇法合成了球形铁磁Co/Ni合金颗粒。XRD、EDX和SEM分析表明，等摩尔的Ni（CH 3COO）（2）中心点4 H（2）O和Co（CH 3COO）（2）中心点4 H（2）O在200 ℃下被乙二醇还原，生成了粒径在200 ~ 500 nm范围内的Co 50 Ni 50合金颗粒。使用振动样品磁强计测量样品在室温下的磁性。Co/Ni颗粒的饱和磁化强度和矫顽力分别为123.21 emu/g和108.23 Oe，表明该合金在室温下具有铁磁性。(C)2005 Elsevier B. V.保留所有权利。
Spherical ferromagnetic Co/Ni alloy particles have been synthesized via a polyol process assisted by solvothermal treatment. XRD, EDX and SEM analyses have shown that the equal molar Ni(CH3COO)(2)center dot 4H(2)O and Co(CH3COO)(2)center dot 4H(2)O were reduced by ethylene glycol at 200 degrees C, resulting in the formation Of Co50Ni50 alloy particles with a narrow particle size ranging from 200 nm to 500 nm. Magnetic properties of the sample at room temperature were measured using a vibrating sample magnetometer. The saturation magnetization and coercivity of the Co/Ni particles exhibit 123.21 emu/g and 108.23 Oe, respectively, which indicates that the alloy is ferromagnetic at room temperature.
