Applied magnetic field angle dependence of the static and dynamic magnetic properties in FeCo films during the deposition

• FeCo films were prepared by electrodeposition method.
• An external magnetic field was applied to induce anisotropy during deposition.
• The direction of applied magnetic field is changed from in-plane to out-plane.
• The magnetic properties of films were investigated by vector network analyzer.
• The in-plane anisotropy is driven by the in-plane component of the field.

FeCo films were prepared by a simple and convenient electrodeposition method. An external magnetic field was applied to the film to induce magnetic anisotropy during deposition. Comparing with the previous work, the angle between the direction of applied magnetic field and film plane is changed from in-plane to out-plane. The influence of the applied magnetic field on magnetic properties was investigated. As a result, it can be found that the in-plane anisotropy is driven by the in-plane component of the magnetic field applied during growth. In addition, the result can also be confirmed by the dynamic magnetic anisotropy of the film obtained by vector network analyzer ferromagnetic resonance technique.
