Adjustable high-frequency magnetic properties of oriented Co80Ir20 soft magnetic thin films with strong negative magnetocrystalline anisotropy
Source abstract
Abstract
The oriented Co80Ir20 soft magnetic thin films with adjustable in-plane uniaxial anisotropy field and strong negative magnetocrystalline anisotropy ( $$K_{\text{u}}^{\text{grain}}$$ ) were fabricated by magnetron sputtering. The oblique angle dependence of the static and high-frequency properties for the oriented Co80Ir20 soft magnetic films was systematically investigated. The results suggest that the in-plane uniaxial anisotropy field (H u) can be adjusted by changing the oblique angle, while the total out-of-plane anisotropy field remains invariable. With the increase in the oblique angle, the value of H u varies from 80 to 310 Oe. As a result, the natural resonance frequency (f r) significantly increases from 4.6 to 7.9 GHz.
