We present results of FMR investigations of anisotropy distribution in uncoupled [NiFe/Au/Co/Au]_N structures with alternating in-plane (NiFe) and out-of-plane anisotropies (Co). It is concluded that for NiFe layers anisotropy distribution is negligible and can be increased by "dusting" of NiFe with ultrathin Co layers. The perpendicular anisotropy K_{U}^2 of Co layers depends on Co thickness in a standard way ∝ 1/d_{Co}, and is distributed in a range of ≈10-20% of K_{U}^2 (i.e., ≈ 1.5× 10^6 erg/cm^3).
