Abstract

Based on density functional theory with the generalized gradient approximation plus on-site Coulomb repulsion method, we study the magnetic-ordering dependence of second-harmonic generation (SHG) in a polar magnet Bi Co O 3 . The large second-order optical susceptibility, which can reach 3.7 × 10 7 esu , exhibits a strong magnetic-ordering dependence, giving rise to magnetic-field controllable SHG response in polar magnets.
