Computational Design of Rare-Earth Reduced Permanent Magnets

Engineering, 2020
Multiscale simulation is a key research tool in the quest for new permanent magnets. Starting with first principles methods, a sequence of simulation methods can be applied to calculate the maximum possible coercive field and expected energy density ...

Stellarators with Permanent Magnets [PDF]

Physical Review Letters, 2020
It is shown that the magnetic-field coils of a stellarator can, at least in principle, be substantially simplified by the use of permanent magnets. Such magnets cannot create toroidal magnetic flux but they can be used to shape the plasma and thus to create poloidal flux and rotational transform, thereby easing the requirements on the magnetic-field ...

Microstructure evolution and metallurgical behavior of (Y/RE)2Fe14B sintered magnets (RE = Nd, Tb)

Results in Physics, 2023
The magnetically hardened shells constructed by the spontaneous core–shell structure due to the enrichment of Y in the core region of (Y/RE)-Fe-B facilitate the enhancement of coercivity.

Effect of grain boundary reconstruction and regenerated main phase shell on magnetic properties in high-abundance (NdLaCeY)-Fe-B magnets

Journal of Materials Research and Technology, 2023
The (NdLaCeY)-Fe-B magnets with 45–50 wt% high-abundance rare earth substitution were systematically investigated by co-mixing high boron content matrix phase and Pr–Fe alloy powders (0, 1, 3, 5, 7, and 9 wt%) during the preparation process.
