摘要

用磁强计研究了在含金水合物存在下，通过旋转-腐蚀分散途径形成的纳米结构的磁性能。由于合成过程中物理化学条件的变化，特别是金的浓度、温度和钢表面初步形成的绿锈或绢云母层的存在，样品的磁性能有明显的差异。所有样品都属于超顺磁性，因此，它们不表现出剩磁和矫顽力。

Magnetic Properties of Nanoparticles Formed on the Steel Surface Contacting with Aurum-Bearing Water Solutions

the magnetic properties of the nanosized structures formed via the rotation-corrosion dispergation route in the presence of aurum aguaforms have been studied using magnetometry. The differences in the magnetic properties of the samples are in evident due to the changes of the physical-chemical conditions during synthesis procedure, especially, aurum concentration, temperature and the presence of the preliminary formed Green Rust or lepidocrocite layers on the steel surface. All samples belong to superparamagnetics, hence, they do not show the remanence magnetization and coercitivity.
