Tohoku U team produces rare-earth-free Fe-Ni magnet with simple industrial technology @TohokuUniPR https://t.co/lp5kHMmO15

Due to shortage of rare-earth elements, which are currently used to produce high-grade permanent magnets, magnets free of rare-earth elements must be developed (i.e., hard magnets based on L10 FeNi). Practically, it is impossible to produce L10 FeNi magnet similar to meteorites industrially because the order-disorder transition temperature of L10 FeNi is too low 320 °C. The diffusion coefficients of Fe and Ni are extremely low around this temperature, and in reality, no diffusion takes place, which is why the ordered L10 FeNi phase requires billions of years to form in cosmic products (meteorites). Since the discovery of the L10 FeNi phase in the 1960s, several attempts (which might trigger atomic migration) such as irradiation with high-energy beams, a nanoparticle technique, mechanical alloying, thin films comprised of mono-layered atoms, and high-pressure torsion techni...
