We report a simple strategy to synthesize anisotropic SmCo₅ nanoplates. The strategy involves the pre-synthesis of 125 x 12 nm Sm(OH)₃ nanorods and 10 nm Co nanoparticles followed by self-assembly of these nanorods and nanoparticles into Sm(OH)₃-Co nanocomposites. Once embedded in CaO matrix, the nanocomposite is subject to high temperature (850 °C) annealing in the presence of Ca, leading to the formation of 125 x 10 nm SmCo₅ nanoplates, which are dispersible in ethanol, allowing the alignment in epoxy resin under a 20 kOe magnetic field. The aligned SmCo₅ nanoplates show a square hysteresis behavior with room temperature coercivity reaching 30.1 kOe, which is among the highest values ever reported for SmCo₅ made from chemical methods. The work provides a new approach to high-performance anisotropic SmCo₅ for permanent magnet applications.
