We perform a systematic materials informatics search for two-dimensional (2D) ferromagnetic materials (2DFM) in the Inorganic Crystal Structure Database (ICSD). The key indicator in the search is that the candidates have a 2D network composed of magnetic atoms and heavy atoms. From the 187,093 entries in the ICSD, the search identified 15 candidates whose magnetic order are then determined by first-principles calculations and Curie temperatures obtained by either analytical solution or Monte Carlo simulation of the 2D Ising model. For the 15 candidates, eight materials have ferromagnetic order including three known structural prototypes and the two 2DFM materials discovered in recent experiments. More importantly, the search produced two new structural prototypes and a very promising material, Cr3Te4, which has a calculated Curie temperature one order of magnitude higher than the others.
