Effect of spin-orbit coupling on spin and orbital ordering in ${\mathrm{Sr}}_{n+1}{\mathrm{Cr}}_{n}{\mathrm{O}}_{3n+1}$ ($n=1$, 2) (opens in new tab)

Author(s): Cristian Fanjul and A. A. AligiaWe incorporate spin-orbit coupling (SOC) into effective Kugel-Khomskii models for the $n=1$ and $n=2$ members of the Ruddlesden-Popper series ${\mathrm{Sr}}_{n+1}{\mathrm{Cr}}_{n}{\mathrm{O}}_{3n+1}$. These models contain interacting spins 1 and pseudospins 1/2 at each site describing spin and orbit…[Phys. Rev. B 113, 235130] Published Tue Jun 16, 2026
