Physical Incorporation of Saccharin Molecules into Electrodeposited Soft High Magnetic Moment CoFe Alloys
نویسندگان
چکیده
Incorporation of saccharin molecules has been studied during the galvanostatic deposition of 2.45 T CoFe alloys. The results indicate that the incorporation rate is strongly dependent on the concentration of saccharin in the plating solution. This dependence showed a pronounced maximum at Csac = 0.12 g L −1, which is a result with significant practical implications. A simple physical model was developed to describe this dependence, having an excellent qualitative agreement with experimental data. The corrosion properties and surface roughness of CoFe deposits were found to be a strong function of saccharin concentration in the plating solution, i.e., the incorporation rate of saccharin molecules. © 2007 The Electrochemical Society.

Sulfur and Saccharin Incorporation into Electrodeposited CoFe Alloys: Consequences for Magnetic and Corrosion Properties
Incorporation of sulfur into 2.4 T CoFe alloys during galvanostatic deposition has been studied. The results indicate that the main source of sulfur in magnetic deposit is saccharin used as an additive in the plating solution. The atomic percent of sulfur in deposit and the sulfur incorporation rate show strong dependence on saccharin concentration in the plating solution. This dependence has p...

The continuous and rapid increase of areal density in magnetic data storage systems required a continuous increase of the coercivity of the storage media. In order to be able to record on these everhigher-coercivity media, new soft magnetic materials for pole tips with increased magnetic moment had to be developed. Significant progress has been made during the last few years in electroplating a...

CoFe/Cu multilayer nanowires were electrodeposited into anodic aluminum oxide templates prepared by a two-step mild anodization method, using the single-bath technique. Nanowires with 30 nm diameter and the definite lengths were obtained. The effect of CoFe layers thickness and annealing on the magnetic behavior of the multilayer nanowires was investigated. The layers thickness was controlled t...
