摘要

Recently current authors have observed NLO effects from magnetic fluids. In this review, we examine all the experimental facts, discuss mechanisms, and com- pare them with numerical calculations. We demonstrate that the thermal diffusion can account for the nonlinear phase shift observed. However, dynamics originates from thermal diffusion in 2-D ap- proximation can only explain the short time behaviors in experiments. We show that even a moderate magnetic field can significantly enhance this NLO effect.
