摘要

在本研究中，采用光学传输和线性二色性的方法研究了制备的磁性液体在100 Oe外磁场作用下的光学特性。采用共沉淀法合成的磁性纳米颗粒、表面活性剂和载体液制备了pH约为7的磁性流体。在磁场垂直于光路的情况下，偏振相关的最大透射差在偏振平行的情况下为40%，在垂直于外加磁场的情况下为20%。当施加与光路平行的磁场时，透射率变化最大，为%10。

Investigation of optical properties of ferrofluid by using magneto-optical transmission and linear dichroism

In this study, optical properties of produced magnetic liquid investigated by means of optical transmission and linear dichroism with respect to applied external magnetic field up to 100 Oe. Magnetic fluid of around 7 pH value were prepared by using magnetic nanoparticles synthesized by the co-precipitation method, surfactant and carrier liquid. Also, polarization dependent maximum transmission difference was measured as 40% for polarization parallel and 20% for polarization perpendicular to the applied field in the case of magnetic field perpendicular to the optical path. Maximum transmission change of %10 was obtained when the applied magnetic field parallel to the optical path.
