origin and applications of Magnetically tunable refractive index of Magnetic Fluid films
Applied Physics Letters, 2004Co-Authors: Shiehyueh Yang, Hernger Horng, Jenje Chieh, Chin Yin Hong, Hongchang YangAbstract:When an external field was applied, the refractive index of the Magnetic Fluid film was observed to be modulated as the field exceeded a critical strength. We found that the stronger the Magnetic field, the higher the refractive index. By taking both the formation of the columns and the variation in the concentration of the liquid phase in Magnetic Fluid films under external Magnetic fields into account, the refractive index was calculated and compared with experimental data. When we did this, we noticed a consistency that implies that the phase separation leads to the variation in the refractive index of the Magnetic Fluid film as the Magnetic field strength is changed. With such a property as a tunable refractive index, the feasibility of using a Magnetic Fluid in a tunable optical device is worthy of investigation.

Magnetically modulated refractive index of Magnetic Fluid films
Applied Physics Letters, 2002Co-Authors: Shiehyueh Yang, Yute Chen, Hernger Horng, Chin Yih Hong, W S Tse, H C YangAbstract:We developed a setup to probe the refractive index of the Magnetic Fluid films under external Magnetic fields. This setup possesses a high resolution of 0.0001 in the measured refractive index. It was found that the refractive index of the Magnetic Fluid depends linearly on the concentration of the dilute Magnetic Fluid under zero field. For a given Magnetic Fluid film, the refractive index increases with the increasing field strength over a critical value, and then becomes saturated as the field reaches around 200 Oe. It is noteworthy that the Magnetically modulated refractive index of the Magnetic Fluid films could have great potential in electro-optical applications.

acute toxicity and irritation of water based dextran coated Magnetic Fluid injected in mice
Journal of Biomedical Materials Research Part A, 2008Co-Authors: Wang Xiaoliang, Wang Xuman, Xie Hong, Gu HongchenAbstract:Based on the elements that Magnetic nanoparticles could heat in an alternating Magnetic field, Magnetic Fluid hyperthermia occurred to inhibit tumor growth in vivo. However, biocompatibility of those Fluids as well as the Fluid-body interaction remains unclear. In this article, acute toxicity and irritation of the water-based dextran-coated Magnetic Fluid (dextran-Magnetic Fluid) injected into mice subcutaneous tissues were examined. Lethal dosage 50 of single treatment with the Magnetic Fluid was 4409.61 +/- 514.93 mg/kg. When injected with 30 mg/0.3 mL dextran-Magnetic Fluid, activities of glutamicoxalacetictransaminase (AST) and glutamicpyruvictransaminase (ALT) and cell number of mice blood did not change statistically. Hemangiectasia and leucocytes infiltration were seen in subcutaneous tissues and these phenomena almost disappeared 72 h later. That is to say, the dextran-Magnetic Fluid was tolerable, safe, and biocompatible. The work is a basic for application of the dextran-Magnetic Fluid in subcutaneous tumor therapy.

laser self induced tunable birefringence of Magnetic Fluid
Applied Physics Letters, 2013Co-Authors: Peng Zu, Hwi Fen Liew, Chi Chiu Chan, Wei Chang Wong, Xinyong DongAbstract:The phenomenon of laser self-induced tunable birefringence of Magnetic Fluid is investigated. This phenomenon exists in Magnetic Fluid, no matter whether it is under an external Magnetic field or not. The variation trend of the laser self-induced birefringence with the laser power follows a linear relationship. Besides, dichroism is not observed in accompany with the laser self-induced birefringence.

Magneto-optical fiber sensor based on Magnetic Fluid
Opt. Lett., 2012Co-Authors: Li Han Chen, Hwi Fen Liew, Yongxing Jin, Chi Chiu Chan, Wen Siang Lew, Yifan Zhang, Wei Chang Wong, Xinyong Dong, Peng ZuAbstract:A novel Magnetic field fiber sensor based on Magnetic Fluid is proposed. The sensor is configured as a Sagnac interferometer structure with a Magnetic Fluid film and a section of polarization maintaining fiber inserted into the fiber loop to produce a sinusoidal interference spectrum for measurement. The output interference spectrum is shifted as the change of the applied Magnetic field strength with a sensitivity of 16.7 pm/Oe and a resolution of 0.60 Oe. The output optical power is varied with the change of the applied Magnetic field strength with a sensitivity of 0.3998 dB/Oe.
