| 摘要: 二乙酰二茂铁间苯二甲酰腙与NiCl2·6H2O在DMSO中反应合成了二乙酰二茂铁间苯二甲酰腙镍配位聚合物(PFZNi)，将其在空气中高温(500～1 200 ℃)热解，并用XRD、XPS、SEM和超导量子强磁计(SQUID)对热解产物进行表征。结果表明，产物是一种纳米NiFe2O4·Fe3O4混合型反尖晶石结构的铁磁相固溶体。在5 K及300 K时，产物有较高的饱和磁化强度(分别为42.57和39.05 emu·g-1)和较低的剩磁(分别为6.87和6.27 emu·g-1)，其磁参数随热解温度而增加。 |

| Abstract: A diacetylferrocenyl isophthalicdihydrazone-Nickel coordination polymer (PFZNi) was synthesized using diacetylferrocenylisophthalic dihydrzone and NiCl2·6H2O as the raw materials in DMSO solvent, and then it was pyrolyzed at high temperatures (500～1 200 ℃) under air， the product was characterized by XRD, XPS, SEM and SQUID. It is found that the product prepared by pyrolysis was a ferromagnetic solid solution with the mixed-type inverse spinel microstructure of nanocrystalline NiFe2O4·Fe3O4. When magnetized by an external field at 5 K and 300 K, it exhibits a higher saturation magnetization (Ms=42.57 and 39.05 emu·g-1) and lower residual magnetism (Mr=6.87 and 6.27 emu·g-1), respectivity, their magnetic parameters increse with pyrolysic temperature. |
