This paper reviews recent developments in research in nanostructured permanent magnets (hard magnetic materials) with emphasis on bottom-up approaches to fabrication of hard/soft nanocomposite bulk magnets. Theoretical and experimental findings on the effects of soft phase and interface conditions on interphase exchange interactions are given. Synthesis techniques for hard magnetic nanoparticles, including chemical solution methods, surfactant-assisted ball milling and other physical deposition methods are reviewed. Processing and magnetic properties of warm compacted and plastically deformed bulk magnets with nanocrystalline morphology are discussed. Prospects of producing bulk anisotropic hard/soft nanocomposite magnets are presented.

“…Furthermore, the surfactant-assisted ball milling (SABM) method has been found efficiently in synthesis of single phase and textured nanostructured REPM compounds [4], however, the coercivity of that, especially for R-Fe-B (R¼ Nd, Pr) system, is very low [3,5,6]. In our previous work, the stoichiometric composition of Pr 12 Fe 82 B 6 nanoflakes with a coercivity of 3.9 kOe was obtained, which is the maximum coercivity of R 2 Fe 14 B (R¼Pr, Nd) nanoflakes or nanoparticles reported up to now [7].…”

“…In addition, up to now, MnAl-based hard magnetic alloys have not been prepared by surfactant-assisted ball milling (SABM) technique yet. As is well known, SABM has drawn great attention recently for the fabrication of high performance anisotropic NdFeB [18,19] and SmCo [20][21][22] hard magnetic nanoparticles and sub-microflakes with controlled particles size and shape.…”

Mn-based alloys are generally thought to be the potential rare earth free permanent magnets with acceptable magnetic properties due to its available high magnetization and anisotropy field. In this work, MnAl and MnGa based alloys have been investigated regarding to their processing, structures and magnetic properties. MnAl based alloys with various C additions and/or trace rare earth doping were prepared by melt spinning. The phase transitions during rapid quenching and post annealing were investigated. The composition and annealing process dependent magnetic properties were obtained. The anisotropic MnAlC flakes with improved magnetic properties were also fabricated by surfactant assisted ball milling using alloy ingot as the precursor. The effects of ball milling and post annealing processes on the phase structure and magnetic properties were discussed. As for Mn-Ga alloy, Mn 70 Ga 30 binary alloy were prepared by melt spinning followed by post heat treatment. The preliminary results show relatively high coercivity. In addition, the prospect of MnAl and MnGa based alloys for permanent magnet applications were discussed in this paper.
