Doubly-doped LiNbO3:Fe:Ni crystals have been grown by Czochralski technique. The transmission spectrum and the effect of light-induced absorption change by ultraviolet (UV) illumination are measured. Nonvolatile holographic storage is realized by red light (633 nm) recording and UV (365 nm) sensitizing. The results show that the saturation diffraction efficiency, the fixing diffraction efficiency, and the recording sensitivity of oxidized LiNbO3:Fe:Ni crystals are higher than those of other reported doubly-doped LiNbO3 crystals. Besides, the nonvolatile holographic recording can't be realized by green light (514 nm) recording and UV light (365 nm) sensitizing. LiNbO3:Fe:Ni has the potential of being a new highly efficient nonvolatile holographic recording material.
