Abstract :
The dependence of the dynamic properties of domain walls in FeNiCo layers on the CoW thickness is investigated. The FeNiCo thickness is about 80 nm. While the FeNiCo layer coercivity increases, domain wall mobility decreases in weak magnetic fields. The observed mechanism of layers interaction is associated with interaction between FeNiCo domain wall stray fields and the CoW layer. The possibility of the increase of coercivity without mobility loss is considered
