“…2, it can be seen that all the ribbons fabricated at different wheel speeds show a sharp crystalline peak. It is difficult to be fabricated as amorphous state by using our melt-spun method unlike the other alloys [11,12]. There is a small amount of RFe 3 (R=Tb, Dy) phase in ribbons that were fabricated at low wheel speeds (o40 m s À1 ) and especially obvious at the wheel speed of 35 m s À1 , but disappears at high wheel speeds (X40 m s À1 ).…”
