Abstract

We report the investigation of the static and dynamic magnetic properties of type- A MnAs Ga0.945 Mn0.055 As (001) bilayers. Static magnetization measurements show them to be ferromagnetically coupled with an exchange bias field of ∼340 Oe. The magnetocrystalline anisotropy constants of the (Ga,Mn)As layer were determined by X -band ferromagnetic resonance (FMR) spectroscopy. The (Ga,Mn)As layers are magnetically inhomogeneous as evidenced by a strong broadening of the (Ga,Mn)As uniform mode linewidth. The MnAs FMR spectra reveal the presence of a small MnAs fraction with a different orientation.
