A rare earth magnet, which is represented by a neodymium magnet (NdFeB) and neodymium magnet films with applications in micro-systems. A method for producing a rare earth magnet, comprising: (a) quenching a molten metal having a rare earth magnet composition to form quenched flakes of nanocrystalline structure; sintering the quenched flakes; subjecting the sintered body obtained to an orientation treatment; and applying a heat treatment with pressurization at a temperature sufficiently high to enable diffusion or fluidization of a grain boundary phase and at the same time, low enough to prevent coarsening of the crystal grains, (b) thick films deposited on a substrate, applying an annealing to crystallize with pressurization at a temperature sufficiently high to enable diffusion or fluidization of a grain boundary phase and, at the same time, low enough to prevent coarsening of the crystal grains.
