Stability study of the pyrochlore iridate metal-insulator transition
Abstract
We seek strain controllable metal insulator transitions(MIT) for use in device applications. This proposal focuses on theoretical calculations on pyrochlore iridate materials geared towards testing a frustration mechanism of such control. We hypothesize that both metallic and insulating forms of magnetism are competing for the ground state due to the special geometry of the lattice. Strain would then distort the geometry and select one of these forms of magnetism and in doing so whether the system is metallic or insulating. Should our calculations predict either this frustration control mechanism or as a byproduct an electronic structure mechanism, we will obtain strong motivation to conduct a future theory-experiment study seeking strain controllable MITs.
