本文研究了（（FexCr_（1-x）II）-Cr-II）（1.5）[Cr-III（CN）（6）]（.）7.5H（2）O和Y1.5Bi 1.5Fe 3.8Al 1.2O 12（Bi，Al：YIG）中磁化诱导的三次谐波（TH）产生。（（FexCr1-xII）-Cr-II）（1.5）[Cr-III（CN）（6）]（.）7.5H（2）O薄膜在外加磁场作用下发生旋转。这种SH旋转归因于沿面外沿着电极化和自发磁化之间的相互作用。特别地，磁线性项chi（ijkL）（magn（1））对SH旋转有贡献。在Bi，Al：YIG磁性薄膜上施加纵向外磁场，TH波的偏振面发生旋转。这种TH旋转可以通过三阶非线性光学极化率中的磁性项chi（yxxxZ）（magn（1））的贡献来理解。(C)2005年美国光学学会
We describe the magnetization-induced second-harmonic (SH) generation in ((FexCr1-xII)-Cr-II)(1.5)[Cr-III(CN)(6)] (.) 7.5H(2)O and the magnetization-induced third-harmonic (TH) generation in Y1.5Bi1.5Fe3.8Al1.2O12 (Bi, A1:YIG). The polarization plane of a SH wave from a ((FexCr1-xII)-Cr-II)(1.5)[Cr-III(CN)(6)] (.) 7.5H(2)O film was rotated by an applied external magnetic field. This SH rotation is ascribed to the interaction between the electric polarization along the out-of-plane and spontaneous magnetizations. In particular, the magnetic linear term chi(ijkL)(magn(1)) contributed to the SH rotation. Applying a longitudinal external magnetic field to a Bi,A1:YIG magnetic film rotated the polarization plane of the TH wave. This TH rotation is understood by the contribution of the magnetic term of chi(yxxxZ)(magn(1)) in a third-order nonlinear optical susceptibility. (C) 2005 Optical Society of America
