Spin-orbit coupling induced magnetic anisotropy and large spin wave gap in $\mathrm{NaOs}{\mathrm{O}}_3$

Avinash Singh, Shubhajyoti Mohapatra, Churna Bhandari +1

The role of spin-orbit coupling and Hund's rule coupling on magnetic ordering, anisotropy, and excitations are investigated within a minimal three-orbital model for the $5d^3$ comp…
