A Systematic Transport And Thermodynamic Study Of Heavy Transition Metal Oxides With Hexagonal Structure, Kamal H. Butrouna

Theses and Dissertations--Physics and Astronomy

There is no apparent, dominant interaction in heavy transition metal oxides (TMO), especially in 5d-TMO, where all relevant interactions are of comparable energy scales, and therefore strongly compete. In particular, the spin-orbit interaction (SOI) strongly competes with the electron-lattice and on-site Coulomb interaction (U). Therefore, any tool that allows one to tune the relative strengths of SOI and U is expected to offer an opportunity for the discovery and study of novel materials. BaIrO₃ is a magnetic insulator driven by SOI whereas the isostructural BaRuO₃ is a paramagnetic metal. The contrasting ground states have been shown to result …
