FIG. 1.

Experimental and calculated results of the field dependent refractive index of the magnetic fluid film. The film thickness is , the concentration of the magnetic fluid is , the working temperature is , and the sweep rate of the field is . The inset shows the images of structure in the magnetic fluid film under external perpendicular magnetic fields.

FIG. 2.

Effective concentration of the liquid phase in the magnetic fluid film vs the magnetic field strength. The original concentration of the magnetic fluid under zero field is , the film thickness is , the working temperature is , and the sweep rate of the field is . The inset plots the linear relationship between the refractive index and the concentration of the magnetic fluid film under zero field.
