摘要：

Spin waves in a sputtered Co85Nb12Zr3 amorphous thin film have been studied by Brillouin scattering in external magnetic fields of up to 3.5 kOe. The spin wave and exchange stiffness constants of the CoNbZr film are determined as D(B) = (2.47+/-0.3) x 10(-9) Oe.cm2 and A = (0.98+/-0.14) x 10(-6) erg/cm, respectively.
