Magnetic anisotropy of epitaxial MgO/Fe/MgO films studied by network analyzer ferromagnetic resonance

The dynamic magnetic properties of MgO/Fe epitaxial thin films are investigated through a network analyzer ferromagnetic resonance in the 0–26-GHz range. The high-frequency response is measured for applied in-plane magnetic fields comparable to the fourfold magnetocrystalline anisotropy of the film,...
