Abstract We have synthesized ternary cobalt alloy using a chemical reduction process using hydrazine as a reducing agent . X-Ray Diffraction (XRD) measurements shows that the synthesized cobalt ternary alloy exists in the pure face centred cubic (fcc) phase with lattice parameter of 3.5562 ± 5 A. The SEM micrograph shows that the particles exist in the spherical shape which suggests that the particles are crystallized in fcc phase. The magnetic properties are determined using Vibrating Sample Magnetometry (VSM) and 59Co IFNMR technique. The saturation magnetization (MS) of the synthesized sample is ~80 emu/g, a slightly lower value compared to the pure cobalt metal. 59Co IFNMR technique shows that there is a broad distribution of hyperfine field (~6 T) compared to the pure fcc cobalt metal. Further, from the deconvoluted NMR peaks suggests that the variation in the nearest neighbours to the central cobalt atom leads to the different hyperfine field.

通过新型低成本化学还原技术合成的 Co35Fe35Ni30 合金的 59Co 内场核磁共振分析

摘要 我们以肼为还原剂，采用化学还原法合成了三元钴合金。X 射线衍射 (XRD) 测量表明合成的三元钴合金以纯面心立方 (fcc) 相存在，晶格参数为 3.5562 ± 5 A。 SEM 显微照片显示颗粒以球形存在，这表明颗粒在 fcc 相中结晶。使用振动样品磁力计 (VSM) 和 59Co IFNMR 技术确定磁性。合成样品的饱和磁化强度 (MS) 为 ~80 emu/g，与纯金属钴相比略低。59Co IFNMR 技术表明，与纯 fcc 钴金属相比，超精细场 (~6 T) 的分布范围很广。更多，
