Abstract
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.
