Article Synopsis
  • Recent discoveries in superconductivity involving infinite-layer nickelates, specifically LaNiO₂, have sparked new research into electronic interactions impacting these materials.
  • Using first-principles simulations, the study reveals that LaNiO₂ displays competing low-energy stripe phases, akin to those found in doped cuprates, driven by complex electronic mechanisms and distortions.
  • The findings highlight the significant role of strong electronic correlations and electron-phonon coupling in the behavior of nickelates, offering insights into electronic inhomogeneity and the absence of long-range order.

We present an in-depth discussion of the magnetic ground state of α''-FeN within the framework of the density functional theory (DFT). The exchange-correlation effects are treated using a variety of schemes, including the local-spin-density approximation, the generalized-gradient approximation, and the Strongly-Constrained-and-Appropriately-Normed (SCAN) scheme. We also delineate effects of adding an on-site interaction parameter on the Fe sites.
