Abstract EN
The magnetic properties of Nd2Fe14B/α-Fe nanocomposite magnets consisting of two nanostructured hard and soft magnetic grains assemblies were simulated for 2D case with random grain distributions generated by a Monte Carlo procedure.
The effect of the soft phase volume fraction on the remanence Br, coercivity Hc, squareness γ, and maximum energy product (BH)max has been simulated for the case of Nd2Fe14B/α-Fe nanocomposite magnets.
The simulation results showed that, for the best case, the (BH)max can be gained up only a several tens of percentage of the origin hard magnetic phase, but not about hundred as theoretically predicted value.
The main reason of this discrepancy is due to the fact that the microstructure of real nanocomposite magnets with their random feature is deviated from the modeled microstructure required for implementing the exchange coupling interaction between hard and soft magnetic grains.
The hard magnetic shell/soft magnetic core nanostructure and the magnetic field assisted melt-spinning technique seem to be prospective for future high-performance nanocomposite magnets.
