由磁性表面活性剂组成的磁性微乳液表现出介于磁性纳米颗粒和分子磁体之间的单畴磁性行为。重要的是，由于表面活性剂分子在水-油界面处的分配，仅观察到表面各向异性。这些新系统允许通过疏水性添加剂的组成和溶解进行原位可调。
Magnetic microemulsions comprising of magnetic surfactants exhibit monodomain magnetic behaviour intermediate between magnetic nanoparticles and molecular magnets. Importantly, due to partitioning of surfactant molecules at the water–oil interface only surface anisotropy is observed. These new systems allow for in situ tunability through composition and the solubilization of hydrophobic additives.
