摘要：

For study of domain topography in antiferromagnetics by nonlinear optical methods such as second-harmonic generation, it is necessary to obtain information on the spectral dependence of the different components of the nonlinear susceptibility tensor chi(ijk) and on their phase. One of the hexagonal manganites, YMnO3 is chosen to demonstrate in detail the experimental methods for obtaining this information. The interference of different contributions is utilized to study domain topography.
