“…The increased use of NdeFeeB magnets in the motors of electric vehicles is hampered by their relatively poor high temperature performance [1,2]. In such automotive applications it is necessary for the magnets to operate for long periods at temperatures up to 150 C [3] With any rare earth transition-metal magnet there are basically two possibilities when it comes to developing coercivity at high temperatures: either we improve the intrinsic temperature dependence of the materials, or we develop sufficient coercivity at room temperature so that enough coercivity remains when the magnet is exposed to high temperatures.…”
