The absorption spectra, photoconductivities and photovoltaic currents of LiNbO 3 : Fe crystals with different Mg doping levels and Li/Nb ratios in the oxidized state have been investigated at room temperature. The Fe 2 รท ions in LiNbO3 : Mg: Fe with Mg content above a critical value are more easily
