Abstract
The substitution effect of Nd for Nb on the structure and magnetic properti es of a Fe84Nb7B9 alloy has been investigated. The substitution of Nd cause s the formation of Fe3B phase in the as-quenched state; Decrease the crysta llization temperature and increase the Curie temperature of the amorphous p hase. After annealing at an optimum temperature; The soft magnetic properti es are improved by substitution of 0.05 to 0.4 at% Nd and Fe84Nb6.9Nd0.1B9 alloy exhibits the permeability (mu') at 1kHz of 39000 and the coercivity ( H-c) of 4.3 A/m.
