The authors report here on the effect of annealing temperatures on the spin wave excitations for the nanocrystalline Fe[sub 88]Zr[sub 7]B[sub 4]Cu[sub 1] alloy, observed from the low temperature magnetization curve and the spectroscopic splitting g factor. The thermomagnetization curve at low temperature is found to obey the Bloch law, M[sub s](T) M[sub s](0)(1 - BT[sup 3/2] - CT[sup 5/2]). From these experimental results, spin wave stiffness constants within the annealing condition were calculated. In addition, effective permeability, coercive force, saturation magnetization (B[sub 10]), magnetostriction and magnetic anisotropy of the annealed alloys have been studied systematically.
