Study of Optical Properties of GaMnN

Mid-gap photoluminescence and magnetic properties of GaMnN films grown by metal—organic chemical vapor deposition

“…According to our previous first-principles calculations [14,15] and the ab initio calculation by using the local spin density approximation in Ref. [16], the crystal field of the lattice splits the fivefold degenerate d shell of Mn into doublet e and pseudotriplet t 2 states.…”
