摘要

Detail studies of the effects of rare-earth substitution on the magnetic properties of bulk amorphous hard magnetic Nd₆₀Fe₃₀Al₁₀ alloys were carried out. Amorphous ribbons of alloys RE₆₀Fe₃₀Al₁₀ (with RE = Nd, Sm, Gd and Dy) were prepared by melt-spinning at 30 m/s. As temperature increases, instead of just a simple transition from ferromagnetic state to paramagnetic state, these ribbons undergo a superparamagnetic stage that ranges over about 100 K. Ribbons of alloys RE₆₀Fe₃₀Al₁₀ with RE = Nd, Sm and Dy exhibit high values of coercivity (in MA/m) range at 4 K, while coercivity of ribbons of alloys with RE = Y and Gd remain low below 100 kA/m).
