Rare-earth permanent magnets are engineered with a complex microstructure of composition and phase, grains and grain boundaries, and it is this complex structure which leads to the magnetic performance. Here, Giron and coauthors, through thorough microstructural analysis, demonstrate that the grain microstructure, not grain boundaries, are primarily responsible for optimal magnetic properties.
