Photostimulated Currents in Single Crystals of Lead Magnoniobate and Lead Magnoniobate Titanate
The spectral dependences of photostimulated currents in single crystals of lead magnoniobate and lead magnoniobate titanate are investigated. The results suggest that the distribution of the density of impurity states in the bandgap of the studied crystals is quite wide. These levels could participate in the formation of diffuse phase transitions.
