The Changes of Magnetic Properties of the Perovskite-Type Titanium Oxides by the Structural Distortions:In the Case of LaTiO3 and YTiO3

摘要

In the perovskite-type titanium oxides,the changes of magnetic properties by GdFeO3-type lattice distortion are observed.In this study,we have performed cluster model calculations based on the density functional theory method,and have obtained the effective exchange integral(J_(ab))in order to elucidate the magnetic change by the GdFeO3-type lattice distortion.The components of deciding the orbital ordering and magnetic property have also been discussed.
