  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.
