J. Shobaki et al., A SCALING MODEL FOR THE OPTICAL ANISOTROPY IN MAGNETIC FLUIDS - DICHROISM AND BIREFRINGENCE, IEEE transactions on magnetics, 32(6), 1996, pp. 5245-5250
A simple scaling model for dichroism and birefringence in magnetic flu
ids is proposed. This scaling is based on two physically measured quan
tities, i.e., the initial slope of the optical anistropy curve with ma
gnetic field, and the saturation value of dichroism or birefringence.
Using this model, the isothermal dichroism and birefringence are super
imposed into a single function. This model is discussed and compared w
ith one similar to that proposed for the magnetization of a superparam
agnetic particle system.
