Abstract—
In the present work, we study mixed compounds based on Ca0.28Ba0.72Nb2O6 (CBN28) calcium–barium niobate, and Sr0.61Ba0.39Nb2O6 (SBN61) strontium–barium niobate single crystals. It is shown that electron radiation in an electron microscope (with an accelerating voltage of 15 kV) during the scanning process induces the enhanced DC conductivity of samples along with a drastic rise in the dielectric constant. Furthermore, the dielectric constant as a function of the temperature changes its course, leading to a strong increase in dielectric loss at frequencies below 10 kHz.
