磁诱导的光学二次谐波及其应用

MAGNETIZATIONINDUCED OPTICAL SECOND HARMONIC GENERATION AND ITS APPLICATIONS

介绍一种新近发展起来的，利用光学非线性效应来进行磁学测量的实验方法———磁诱导的光学二次谐波．该方法不仅对于表面的对称性及磁性结构具有极高的探测灵敏度，更重要的是它还是现在极少数可对多层薄膜的界面进行研究的技术，这为当今非常活跃的磁性单层、多层膜的研究工作提供了一个强有力的手段．

A new technique magnetization induced optical second harmonic generation,which uses nonlinear optical effects for magnetic studies.It is one of the few techniques that can be used to study the buried interface of magnetic multilayers, and has become a powerful tool for studying magnetic films due to its extreme sensitivity in detecting interface symmetry and interface magnetic structure.
