Computational Design of Rare-Earth Reduced Permanent Magnets [PDF]
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]
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)
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.

Characterization of Permanent Magnet Magnetization [PDF]
The performances of electrical machines highly depend on the behavior of materials, such as steel, copper, and permanent magnet. This paper focuses on permanent magnets whose magnetization must be precisely known. Thus a non-destructive approach which includes a combination of experiments and inverse problem, using the magnetostatic moment method, is ...
