The present invention relates to the technical field of superlattice magneto-optical material technologies, and in particular, to a superlattice material, and a preparation method and application thereof. According to description of embodiments, the superlattice material provided in the present invention has both a relatively good magnetic property of a ferrous garnet material and a good photoelectric absorption characteristic of a two-dimensional semiconductor material such as graphene. Magneto-optical Kerr effect data obtained through testing shows that: A saturated magneto-optical Kerr angle of the superlattice material in the present invention is 13 mdeg in a magnetic field of 2500 Oe, and a magneto-optical Kerr angle of the superlattice material is increased by 2.5 times compared with a nonsuperlattice ferrimagnetic thin film material into which no two-dimensional material is inserted, thereby achieving magneto-optical effect enhancement.
