Abstract

We employ density functional theory using the modified Becke-Johnson (mBJ) approach to investigate the electronic and magneto-optical properties of N-doped NaTaO $_{3}$ . The mBJ results reveal a half metallic nature of NaTaO $_{2}$ N, in contrast to results obtained by the generalized gradient approximation. We find a giant polar Kerr rotation of 2.16 $^{\circ}$ at 725 nm wave length (visible region), which is high as compared to other half metallic perovskites as well as to the prototypical half metal PtMnSb.
