文摘
- •
Fe80Ni20 NWs with lengths up to 60 μm were fabricated into hard-AAO templates.
- •
Interwire and intrawire magnetostatic interactions were investigated by angular FORC diagrams.
- •
Irreversible angular dependence of coercivity was used to describe magnetization reversal modes.
- •
A single vortex state with broad nucleation and annihilation fields was detected at θ=83°.
- •
A good agreement between the experimental findings and analytical models was obtained.
