Thin (∼1000 Å) films of (Fe[sub 54]Co[sub 46]) [sub 1-χ]Cr[sub χ] have been prepared by magnetron sputtering on Si/SiO[sub 2] substrates. The films were shown to be body-centered-cubic and (110) textured. It was found that the Fe[sub 54]Co[sub 46] films possess a saturation magnetization of 24.5 kG at room temperature. Doping the Fe[sub 54]Co[sub 46] films with Cr in the range of 0-13 at. % increased corrosion resistance, electrical resistivity, and reduced the saturation magnetization as a function of the amount of added Cr. The coercivity of both doped and undoped as-deposited films (80-120 Oe) decreased substantially after a 220 °C magnetic anneal. Electrochemical corrosion testing was done in two chloride salt solutions. Potentiodynamic scans performed on films in a 0.47 M chloride bath solution at pH = 2.9 showed a substantial increase in corrosion resistance of the films between 6.6 and 8.2 a/o Cr. Similar scans performed in a 0.01 M chloride solution at pH = 5.8 showed good corrosion resistance for all the films. [ABSTRACT FROM AUTHOR] |
