摘　　要：本文基于磁液磁致双折射效应,实现了其磁光双稳特性的研究。理论上,建立了其磁光双稳传输模型、进行了计算机模拟,并在此基础上建立了相应的实验分析系统。研究表明:磁液薄膜具有良好的磁光双稳特性,可用作超长波红外波导器件。Based on its atrong magneitcally induced birefringence, this paper deals with the research of the magneto-optical bistable characteristics of a ferrofluid thin film. An optical transmission model is proposed and an experimental system is set up to analyse its dependence on the system parameters. Experiments show that the ferrofluid thin film behaves good characteristics of optical bistability and can be used as ultra-long wave optical waveguide devices.
