On the comparison of the polarisation behaviour of exchange-biased AF/F NiMn/Fe37Co48Hf15 bi-layer and multi-layer films with increased ferromagnetic cut-off frequencies

► Static and dynamic properties of NiMn/Fe37Co48Hf15 bi- and multi-layer films. ► Theoretic analysis of the Heb- field difference of bi- and multi-layer films. ► Two-stage magnetic process in the polarisation curves of the AF/F multi-layers. ► Damping at the ferromagnetic permeability resonance state of AF/F multi-layers. ► Derivation of the ferromagnetic resonance of AF/F multi-layer films.
