Implication

Micromagnetic simulations examine how microstructure affects coercivity and remanence in Nd-Fe-B magnets, indicating pathways for performance optimization.

Key Points

This research investigates how microstructural features influence the magnetic properties of Nd-Fe-B permanent magnets.
Utilized Hybrid Monte Carlo micromagnetics simulations.
Constructed a polycrystalline model using Voronoi tessellation.
Adjusted microstructural parameters to study grain boundary effects.
Wider grain boundaries reduced coercivity by 32% and remanence by 16%.
Grain boundaries facilitated nucleation of reverse domains, especially at junctions.
Increased easy-axis tilt angle lowered coercivity due to effective anisotropy reduction.
