摘　　要：以Fe2(SO4)3、ZnSO4·7H2O为主要原料通过水热合成法制得了纳米ZnFe2O4超细粉末,利用X-射线衍射(XRD)、透射电子显微镜(TEM)、红外光谱(IR)和VBH-55样品磁强计(VSM)等手段对样品进行了表征,结果表明:水热法制备的纳米ZnFe2O4颗粒,大小均匀(7～10nm),无团聚;磁性能测试表明该纳米ZnFe2O4具有亚铁磁性,并对其机理进行了探讨。Nanosize ZnFe_2O_4 powder zinc ferrites were fabricated by hydrothermal precipitation route using Fe_2(SO_4)_3, ZnSO_4·7H_2O as raw material, and studied by XRD, TEM, IR and VSM. The results showed that the products were uniformly sized nanoparticles (7～10 nm) without aggregation; and sub-ferrimagnetic behaviors of the synthesized ZnFe_2O_4 samples were confirmed by magnetic characterization.The mechanism of the sub-ferrimagnetic behaviors was also discussed.
