Influence of magnetic annealing on high-frequency magnetic properties of FeCoNd films

► FeCoNd thin film with thickness of 166 nm shows the perpendicular anisotropy. ► Perpendicular anisotropy decreases as annealing temperature increases from RT to 573 K. ► In-plane uniaxial anisotropy is achieved as annealing temperature above 400 °C. ► The resonance absorption phenomena around gigahertz were observed for FeCoNd films. ► The as deposited FeCoNd films have much potential for high-frequency application.
