摘要:

我们报告的化学合成路线,结构表征,和物理性能的纳米流体磁性石墨(NFMG)从先前合成的块状有机磁性石墨(MG)通过稳定的水磁性流体悬浮液与活性阳离子表面活性剂的添加。测量的磁化场磁滞曲线以及磁化强度的温度依赖性证实了MG和NFMG样品的室温铁磁性。

英文摘要:

We report the chemical synthesis route, structural characterization, and physical properties of nanofluid magnetic graphite (NFMG) obtained from the previously synthesized bulk organic magnetic graphite (MG) by stabilizing the aqueous ferrofluid suspension with an addition of active cationic surfactant. The measured magnetization-field hysteresis curves along with the temperature dependence of magnetization confirmed room-temperature ferromagnetism in both MG and NFMG samples.
