اقرأ أكثرFor example, the magnetic moments of paramagnetic Nd and Dy are 3.68 μB and 10.6 μB, respectively. The separation factors of Nd/Lu and Dy/Lu are increased by 17% and 47%, with a difference of 20%. Therefore, the larger the magnetic moment difference of rare earth ions, the greater separation factors of different rare earth ions are.
