Ferromagnetic resonance (FMR) measurements at X‐band frequencies are used to study in‐plane magnetic anisotropies of a number of molecular‐beam epitaxy (MBE) Co/Cu(111) multilayer films. X‐ray and reflection high‐energy electron diffraction (RHEED) measurements confirm the epitaxial growth of Co on Cu(111) with f.c.c.(111) structure. The FMR experimental data are fitted by using energy density expressions that include a combination of growth induced uniaxial (second‐) and sixth‐order anisotropies. Values for the effective demagnetizing field (4π M s ) eff , the growth induced uniaxial field H Ku ' and the sixfold in‐plane anisotropy field H K4 parameters are obtained from a multi‐parameter χ 2 function minimization routine.
