摘要：

The magnetic performance of hard-/soft-phase nanocomposites depends on their microstructure. Nanocomposites with an inter-granular phase, fabricated via a physical route, are fascinating as they can further enhance the magnetic properties of hard-/soft-phase nanocomposites. In this study, the magnetic performance is estimated on an isotropic Nd2Fe14B/a-Fe nanocomposite system with an inter-granular phase via micromagnetic simulation. The simulated results show that the magnetic performance of the system is strongly dependent on the size of Nd2Fe14B particles and the thickness of a-Fe phase. The simulated energy product provides a good approximation to the experimental one. The optimal size of Nd2Fe14B particles and thickness of the a-Fe phase, which give the highest energy product, are found. The simulation is expected to contribute to the preparation of high-performance isotropic Nd2Fe14B/a-Fe nanocomposite magnets with an inter-granular soft-magnetic phase.
