Abstract
Using Landau-Ginzburg-Devonshire theory we study the complex interplay between structural antiferrodistortive order parameter (oxygen octahedron rotations), polarization and magnetization in EuxSr1-xTiO3 nanotubes and nanowires. We calculated EuxSr1-xTiO3 bulk and nanosystem phase diagrams, which include the antiferrodistortive, ferroelectric, ferromagnetic and antiferromagnetic phases. Our calculation shows the presence of "triple" antiferrodistortive-ferroelectric-ferromagnetic phases for EuxSr1-xTiO3 nanowires and nanotubes. presents interest for fundamental study and can be important for their potential applications. Since the triple phase exists at low temperatures (<10 K) with high polarization and magnetization values (~50 muC/cm2 and ~0.5 MA/m2). Therefore, the strong coupling between structural distortions, polarization and magnetization suggest the EuxSr1-xTiO3 nanosystems as strong candidates for possible miltiferroic applications.
