Abstract: In this work, the static and dynamic magnetic properties of FeCoN films with various thickness have been studied. By controlling the deposition conditions, two-fold static anisotropies, namely a perpendicular anisotropy and an in-plane anisotropy, are introduced into the films, forming weak stripe domain. It is found that, for the films with the thickness between 130 nm and 240 nm, the anisotropy of FMR response is switchable. More importantly, the switching field of the dynamic anisotropy is only about 40-50 Oe, which is far below the value required to switch traditional rotatable anisotropy. Combined with high magnetic permeability and low-field switchable anisotropy, these films are promising for practical applications in the microwave devices. © 2017 Author(s).
