Magnetism-induced second-order nonlinear optical responses in multiferroic BiFeO
Babu Baijnath Prasad, Guan-Fu Liu, Guang-Yu Guo
Nonlinear optical (NLO) responses of noncentrosymmetric nonmagnets have drawn a lot of attention in the past decades because of their significance in materials characterization, gr…
