In this paper, a new hydrocarbon-based magnetic fluid containing CdFe2O4 nanoparticles was investigated using static magnetic birefringence (SMB) and transmission electron microscopy. Inclusion of the dependence of the birefringence signal upon both the magnetic permeability and the formation of chain-like structures yields excellent agreement between the SMB data and the model used to fit them.
