摘要：
The mode mismatched thermal lens technique was used in the determination of thermal diffusivity of oriented lyotropic liquid crystal doped with ferrofluid. It was found that the behavior of the parallel thermal diffusivity as a function of ferrofluid content could not be explained in terms of the order parameter alone. Additional contribution coming from the ferrofluid itself seems to be necessary for the interpretation of the experimental data.
