Dielectric Constant of Strontium Titanate at Low Temperatures

Abstract

It has been reported that SrTiO₃/ becomes ferroelectric below about 50 deg K. When SrTiO₃ is compared with well known ferroelectrics such as BaTiO₃, remarkable contrasts are found in their dielectric properties. The dielectric constants are examined in three directions: STA110!, STA111!, and STA100!. (W.D.M.)
