Abstract
Fe-K(3+)-O-i(2-) impurity centers in a KTaO3 sample to which a dc electric field E = 75 kV/cm is applied are shown to be oriented at temperatures T gr eater than or equal to 120 K. In these conditions, the effective local fiel d acting on the electric dipole moment of a center exceeds the applied fiel d by a factor 7.6. (C) 2000 MAIK "Nauka/Interperiodica".
