Spin--orbit-enhanced correlation sensitivity and anomalous magnetic response in non-dimerized 4d 4 ilmenite CdRuO 3
The study investigated CdRuO3 to see if its non-dimerized structure supports a metallic state. It found that while the structure is non-dimerized, spin-orbit coupling significantly enhances correlation effects, causing a direct energy gap to open at specific conditions where it was previously absent. This shows that structural distortion and electronic interactions compete without simple dimerization.
