KRB1 Method for preparing rare earth permanent Sintering behavior of spin coated FePt and FePtAu
The present invention relates to a method for preparing a rare earth permanent magnet The method for preparing a rare earth permanent magnet comprises a step of preparing a magnet raw material alloy a step of crushing the alloy a step of pulverizing the crushed alloy powder and a step of sintering the finely pulverized alloy powdersintering7 In summary the spin coated FePt and FePtAu nanopar ticles have a hcp ordered superstructure The annealing pro cess which is needed to achieve hard magnetic properties destroys the assemblies via agglomeration and sintering based on SANS and magnetic measurements This effect is more pronounced for FePtAu nanoparticles than for FePt
