The magnetic properties of cobalt films deposited electrolytically on Au(1
1 1) have been studied by ferromagnetic resonance. A sixfold contribution o
f the magnetic anisotropy, much smaller than in bulk cobalt, is detected. T
he sixfold magnetic anisotropy of hep(0 0 0 1) and fcc(1 1 1) Co decreases
with increasing film thickness due to increasing misalignment of the prefer
red orientation of the Co crystallites. (C) 2001 Elsevier Science B.V. All
