Magnon Brillouin scattering from an amorphous CoNbZr thin film

Spin waves in a sputtered Co 85 Nb 12 Zr 3 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)×10 -9 Oe ·cm 2 and A =(0.98±0.14)×10 -6 erg/cm, r...
