Abstract :
Ternary DyFeB nanoparticles and nanoflakes were prepared by surfactant-aid high-energy ball milling. As the particle size decreases, the coercivity decreases from 16.8 to 0.4 kOe, indicating substantial influence of the size on the coercivity of the particles. In addition, strong magnetic anisotropy was achieved in magnetically aligned DyFeB nanoflakes.
