The present invention discloses a type of R-Fe-B current production method of the sintered magnetic material. The main steps are R-Fe-B stream prepare a sintered magnet as a main material, and containing the following RXE layer rare earth element of of them to place RXE is the on state material surface in powder RX, of the organic solid that it includes powders EP, organic organics EP, ET is the main material in RXE layer, wherein the main material to form an organic thin film layer surrounding the rare earth element of the main material surface after the composition is dried treated with solvent ET in the heating process, a heat treatment in a vacuum sintering an exit, and rare earth element in the RX of the spread of a magnetic material increases the internal magnetic body chair performance. The advantages of the present invention the thickness of the layer is not uniform, RXE easily peeled off, and EP, organic materials containing ET, even if departing from the primary material from the heat treatment does not increase the basic carbon element content is significant.
