摘要：

Hexagonal perovskites Ba3TiRu2O9 and Ba3ZrRu2O9 are investigated in the framework of density functional theory (DFT) utilizing the generalized gradient approximation plus Hubbard (U) (GGA + U) and modified Becke Johnson (GGA + mBJ) potential. Stable magnetic phase energies and magnetic susceptibility describe the antiferromagnetic (AFM) nature of Ba3TiRu2O9 and paramagnetic (PM) nature of Ba3ZrRu2O9. The electronic band profiles of these perovskites in their respective magnetic phases and electrical resistivity show that both compounds are metallic in nature. Due to high Neel temperature and AFM nature makes Ba3TiRu2O9 suitable candidates for spintronic and magnetic cloaking applications while PM metallic nature of Ba3ZrRu2O9 make it useful for biological applications to control signal to noise ratio
