Interpretation of electric field effects in EPR of Gd³⁺ in SrTiO₃

Abstract

The electric field effects in EPR of Gd3+ substitutional for Sr2+ in SrTiO3 observed by Unoki and Sakudo below 65°K, especially the rotation of the magnetic axes are shown to be compatible with the accepted I 4/mcm structure existing below the strutural transition at 105°K and the dielectric properties of the crystal. © 1971.
