Abstract

The optical effects of dichroism, static light scattering, and light attenuation under the action of a magnetic field in magnetic fluids with an average particle size of 6.7 and 13.7 nm were studied. Significant differences were found both in the magnitude of the effects and in their spectral behavior. They can be due to the formation of aggregates in the sample with larger particles, which significantly change the optical properties of the system. The formation of aggregates under the action of the field was confirmed by dynamic light scattering.

不同抗聚集性磁性流体中的光吸收和光散射

研究了平均粒径为 6.7 纳米和 13.7 纳米的磁性流体在磁场作用下的二色性、静态光散射和光衰减等光学效应。研究发现，这些效应的大小及其光谱行为都存在显著差异。这可能是由于较大颗粒的样品中形成了聚集体，从而显著改变了系统的光学特性。动态光散射证实了聚集体在磁场作用下的形成。
