The extremes in the dependences of integrated dynamic susceptibility components are observed at low fields.

Lower extremes can be observed at a shift of the localization of the lower FMR mode toward the interface between the layers.

The features of the distribution of the dynamic susceptibility over the thickness have been discussed.

The cubic anisotropy leads to the fact that the off-diagonal integrated dynamic susceptibility components are essential.

FMR signal can be excited in vicinity of the interlayer boundary.
