Nanosized Anisotropic Sm–Fe–N Particles with Metastable TbCu7-Type Structures Prepared by an Induction Thermal Plasma Process [PDF]

Nanomaterials
TbCu7-type Sm-based compounds can be produced in bulk and potentially surpass Nd2Fe14B as permanent magnets. However, as the processes to prepare anisotropic magnetic particles are limited, the full potential of TbCu7-type Sm-based compounds cannot be ...
