摘要
The paper is supposed to find the change of the light transmission rate with the change of time of the same volume fraction of ZnFe2O4ferrofluids, FeOOH ferrofluids and FeOOH-ZnFe2O4binary ferrofluids, applied in different magnetic field, in parallel to the light direction. The field-induced effects of light transmission for the three ferrofluids are compared, so as to explore the reason from the microstructure change of the ferrofluids.
