In situ fabrication of Co90Nb10 soft magnetic thin films with adjustable resonance frequency from 1.3 to 4.9 GHz

In this work, we realized in situ fabricated Co90Nb10 soft magnetic thin films, with variable in-plane uniaxial magnetic anisotropy, without using the field induced method or postfabrication treatment. In situ control over the in-plane uniaxial magnetic anisotropy field, which varied from 1.6 to 22.7 kA m(-1), was achieved by adjusting the deposition oblique angle from 0 degrees to 38 degrees. As a consequence, the resonance frequencies of the films were continuously increased from 1.3 to 4.9 GHz. (c) 2008 American Institute of Physics.
