Abstract

NdFeB system nanoparticles using the mixture of NdFeB-oleate complexes under the pressure of 40 Pa at 380degC with argon gas without any solvent are formed by thermal decomposition method. The produced NdFeB system nanoparticles were collected as colloidal solution of CHCl3. The morphology and size of prepared NdFeB nanoparticles were investigated with transmission electron microscopy (TEM). The chemical composition was determined by electron probe X-ray micro-analyzer (EPMA). The crystal structure of the nanocomposite was corroborated by using X-ray powder diffraction (XRD). The magnetic property was measured with super conducting quantum interference device (SQUID). (Abstract)

钕铁硼磁性纳米颗粒的合成与性能研究

利用NdFeB-油酸盐配合物的混合物，在380℃、40 Pa的压力下，与不含任何溶剂的氩气结合，采用热分解法制备了NdFeB体系纳米颗粒。制备的NdFeB纳米颗粒作为CHCl3的胶体溶液收集。用透射电镜(TEM)研究了制备的钕铁硼纳米颗粒的形貌和尺寸。用电子探针x射线微量分析仪(EPMA)测定其化学成分。利用x射线粉末衍射(XRD)对纳米复合材料的晶体结构进行了确证。利用超导量子干涉仪(SQUID)测量了材料的磁性能。(抽象)
