Selective suppression of electronic orders via interlayer coupling in superconducting bilayer nickelate thin films
The study investigated how tuning interlayer coupling in nickelate thin films selectively suppresses competing electronic orders. By using A-site rare-earth substitution and ozone annealing, researchers found methods to suppress the spin-density-wave (SDW) order while eliminating a second charge-like anisotropy order, revealing distinct mechanisms controlling these different electronic states.
