A systematic microscopic theory of magnetically induced ferroelectricity and lattice modulation is presented for various electron configurations of Mott-insulating transition metal oxides. The origin of polarization is classified as the spin-orbit interaction effective (i) within the magnetic t(2g) orbitals, (ii) between the t(2g) and e(g) orbitals, and (iii) within the ligand ion's p orbitals. Predictions for x-ray and neutron scattering experiments are proposed to clarify the microscopic mechanism of the spin-polarization coupling in different materials. Semiquantitative agreements with the multiferroic TbMnO3 are obtained.
