摘要：

We studied the effects of Saccharin on the properties of electroplated Ni-Fe Permalloy thin films. When 0 to 1 mu mol/L of Saccharin was added to the plating electrolyte, the grain sizes of the deposits are found to decrease, which reduces the surface roughness and the coercivity and increases the permeability and magnetoimpedance. The reduction in the grain sizes is strongly correlated with increases in the incremental permeability and the magnetoimpedance. We demonstrated that Saccharine is a useful additive for the electrodeposition of soft Permalloy thin films and that the softness can be adjusted by varying the concentration of Saccharin.
