摘要
在磁性高分子材料的研究中，为了获得磁性能高、粒径小和稳定性好的纳米晶磁核，作者对ＣｒｘＦｅ３－ｘＯ４纳米晶磁性载体的制备和性能作了研究。通过化学共沉淀法制得的ＣｒｘＦｅ３－ｘＯ４纳米晶，具有２０－３０ｎｍ的粒径，比饱和磁化强度σｓ≥５０ｅｍｕ／ｇ。
In order to obtain magnetic nanocrystalline materials with high magnetism,tiny particle size and good stability,the author has made researches on preparation and porperties of Cr xFe 3-x O 4 nanocrystalline magnetic carrier.The nanocrystallite prepared by chemical coprecipitation method has particle size of 20 30nm,saturation magnetization a s≥50emu/g and coercivity H C about three times as high as that of pure Fe 3O 4.
