Effect of Temperature on the Optical Properties of Magnetic Fluids Containing Aggregates of Nanoparticles
摘要
Abstract
The influence of temperature on the optical properties of an aggregation-prone magnetic fluid was studied. It was found that temperature affects magnetic birefringence and dichroism, as well as light scattering and transparency of samples. These effects may be associated with a decrease in the size of magnetite nanoparticle aggregates upon heating.
