Cooling rate is the key factor affecting soft magnetic properties of amorphous ribbons. So, is the faster the cooling rate conducive to better soft magnetic performance as theoretical hypotheses? The uncertainty of the debate on this issue in practical application motivates the present work. (Fe0.9Co0.1)86Ni1B13 amorphous ribbons with different thicknesses were prepared by deliberately varying the cooling rate. It was found that the amorphous ribbon prepared at a lower cooling rate exhibits better soft magnetic properties than the one prepared at a higher cooling rate. The reasons behind the improvement of the soft magnetic properties of amorphous ribbons were investigated in this work. The results prove that cooling rate strongly affect the surface morphology and residual stress of amorphous ribbons and thus the magnetic structure and properties of amorphous ribbons. On the premise of ensuring the formation of amorphous structure, high surface quality and low defects density of the ribbon prepared at low cooling rate promise candidates for the potential application in electric devices rather than the ribbons prepared at a high cooling rate.
