Abstract

The deposition kmetics and the magnetic properties of Co x-Fe1-x (30<x<40) soft magnetic films (< 10000 Å) obtained by electroless deposition were investigated. In particular, the effect of film thickness on easy-axis coercivity was studied. Three organic additives were used: sodium saccharin, saccharin and maltose. In the initial stages of the deposition process, maltose greatly inhibits Co-Fe deposition if compared to sodium saccharin and saccharin Néel coefficient calculated from the log-log plot of easy-axis coercivity (Hc) vs. film thickness in the range above 600 Å are - 0.23 and -0 3 for sodium saccharin and saccharin, respectively. On the other hand, Co-Fe ultra-thin films deposited from maltose-containing baths showed no dependence of Hc on films thickness in the same range. The uniaxial magnetic anisotropy induced during deposition was also investigated. copyright The Electrochemical Society.
