Abstract
Wide band gap layered single crystals CdI2 (4H) have close-packed hexagonal lattice. Doped with CuI and NiI2 crystals for investigations were grown from the melt by the Bridgman method. The layered crystals possess surfaces of high quality (mirror-like quality), which are parallel to the layers. Doping improves nonlinear properties of crystals CdI2; in particular increases the efficiency of generation of the second harmonic (SHG). SHG temperature dependencies in NiI2 and CuI-doped crystals are investigated. All studied samples were pre-treated in magnetic fields at 4.2 K for 4 hrs. SHG signal decreases with temperature. Thus the ordering in impurity atom location is accompanied by the appearance of polarization charges on crystals surface and by increased lattice eccentricity.
