Quest for New Quantum States via Field-Editing Technology
Abstract
We report new quantum states in spin-orbit-coupled single crystals that are synthesized using a game-changing technology that "field-edits" crystal structures (borrowing from the phrase "genome editing") via application of magnetic field during crystal growth. This study is intended to fundamentally address a major challenge facing the research community today: A great deal of theoretical work predicting exotic states for strongly spin-orbit-coupled, correlated materials has thus far met very limited experimental confirmation. These conspicuous discrepancies are due chiefly to the extreme sensitivity of these materials to structural distortions. The results presented here demonstrate that the "field-edited" materials not only are much less distorted but also exhibit novel phenomena absent in their "non-edited" counterparts. The field-edited materials include an array of 4d and 5d transition metal oxides, and three representative materials presented here are Ba4Ir3O10, Ca2RuO4, and Sr2IrO4. This study provides an entirely new paradigm for discovery of new quantum states and materials otherwise unavailable.
