Abstract
Ferromagnetic resonance in 1000-Ɨ-thick Co films evaporated on sapphire, glass or MgO substrates has been studied. An effective uniaxial anisotropy field (Hk) of -16.27 kOe and gyromagnetic ratio (े/2ॠ) of 3.10 GHz/kOe were obtained for Co film on sapphire. Assuming the saturation magnetization (4ॠM) of 17.58 kG, we derived a small intrinsic perpendicular anisotropy field (HkC4ॠM) of 1.31 kOe.
