High coercivity permanent magnet materials based on iron-rare-earth-carbon alloys
N.C. Liu,Hans H. Stadelmaier +1 more
TL;DR: The class of tetragonal iron-rare-earth-boron compounds that produce high performance permanent magnets has been expanded by identifying isostructural carbides that have high magnetocrystalline anisotropy as discussed by the authors.

High intrinsic coercivities in iron‐rare earth‐carbon‐boron alloys through the carbide or boro‐carbide Fe14R2X (X=BxC1−x)
TL;DR: In the phase Fe14R2X, where R is a lanthanide and X is either boron or carbon, or a mixture of the two, the extent of stability of the carbides and their miscibility with the borides is traced for the lighter rare earth metals as discussed by the authors.

Preparation and magnetic properties of R-Fe-B permanent magnet materials containing Fe3B as the main phase
R Reinder Coehoorn,C. de Waard +1 more
TL;DR: The coercivity of permanent magnet materials can be improved to approximately 0.45 T by partial substitutions of the rare earth atoms by Tb or Dy as discussed by the authors, which leads to low coercivities due to the formation of the magnetically soft phase R3Fe62B14.

Relationships between crystal structure and magnetic properties in Nd 2 Fe 14 B
TL;DR: In this article, the crystal structure and intrinsic magnetic properties of transition-metal materials have been determined by considering analogies with previously known rare-earth transition metal materials, and it has been demonstrated that permanent magnets having large coercivities and energy products can be formed from this phase, underscoring its potential technological importance.
