Grain Boundary Distortion Reorients the Local 4f Easy Axis and Splits Light from Heavy Lanthanides in Nd2Fe14B
Avik Mahataa, M. Zakotnik
The coercivity of rare-earth permanent magnets originates from the crystal field acting on localized 4f electrons, yet how grain boundaries modify the underlying single-ion Hamilto…

First Principles Thermodynamics of Zr B Segregation at Grain Boundaries in Recycled Nd2Fe14B
Avik Mahata, Miha Zakotnik
Grain-boundary chemistry is central to the coercivity and thermal stability of Nd2Fe14B permanent magnets, particularly in recycled magnets where recovery of the hard-magnetic phas…
