Abstract

Multiphase nano-structured permanent magnets show a high thermal stability of remanence and a high energy product while the amount of rare-earth elements is reduced. Non-zero temperature micromagnetic simulations show that a temperature coefficient of remanence of -0.073%/K and that an energy product greater than 400 kJ/m³ can be achieved at a temperature of 450 K in a magnet containing around 40 volume percent Fe₆₅Co₃₅ embedded in a hard magnetic matrix.
