Effects on particle diameter and magnetic force of magnetic ultra-fine particle that depend on surface-active agents and ph condition in its synthesis
説明
We clear it in this research that the character of the magnetic fluid changes greatly by the kind of saccharide (surface-active agents). Furthermore, we state that two essential factor of this magnetic fluid, which are the particle diameter and the magnetic force, can be controlled by the variety of surface-active agents and the various conditions in the synthesis. The ultimate saturation magnetization is 24.0[emu/g] and the average diameter of whole particle including surface-active agents can be controlled from 74.5[nm] to 455.1[nm].
