Abstract
In this work, the ferromagnetic resonance modes are worked out considering in-plane anisotropy and out-of-plane anisotropy, respectively, in ferromagnetic/antiferromagnetic bilayer films. The ferromagnetic resonance frequency, magnetic susceptibility, and field linewidth with stress anisotropy have been investigated by using ferromagnetic resonance method. The results show that while applied magnetic field is applied along some directions, the ferromagnetic resonance frequency can be enhanced and field linewidth can be broaden by increasing the intensity of stress anisotropy field. Furthermore, the effect of stress anisotropy field proves substantially stronger for out-of-plane anisotropy than in-plane anisotropy.
