Nanoscale Electronic Phase Separation Driven by Fe-site Ordering in Fe\textsubscript{5-x}GeTe\textsubscript{2}
By combining high-resolution scanning tunneling microscopy with density functional theory, this study reveals that Fe-site ordering in the van der Waals ferromagnet FeGeTe drives nanoscale electronic phase separation, where ordered Fe(1) domains exhibit metallic behavior while deficient regions display pseudogapped states due to symmetry-allowed Fe 3d-Te 5p orbital hybridization.
