摘要：
The BaTiO3 and SrTiO3 crystals have many technological applications due to their unusual magnetic and dielectric properties. Using the INDO method modified for crystals which had shown reliability in a number of applications, we study self-trapped and impurity-trapped polarons in cubic lattices of both materials and La-doping of the SrTiO3 crystal. The obtained results are discussed in terms of the available experimental data.
