| Abstract: | The influence of  treatment in a magnetic field at low temperatures on the nonlinear optical properties of NiI2-doped CdI2 single crystals is investigated. The impurity ions in the interlayer space or more complex centers into which these ions enter can align on exposure to a magnetic field due to the interaction with the membrane vibrations of the lattice and create residual polarization in a specimen. This polarization causes redistribution of the electric charge on the bonds and improves the nonlinear optical properties of single crystals. |
