Brandt, Martin S. Köder, Andreas eng Gönnenwein, Sebastian T. B. Frank, Sebastian 2021-04-29T14:00:50Z Wassner, Thomas We report on ferromagnetic resonance measurements of Ga<sub>1−x</sub> Mn <sub>x </sub>As thin films with Mn contents 0.022 ≤ x ≤ 0.051. For x ≥ 0.036 and the external magnetic field normal to the thin film, we observe several resonances, which we identify as spin wave resonances. The non-quadratic mode spacing can be consistently explained by a linear gradient in the magnetic properties of the films. From the measurements, the exchange constant A can be deduced for different Mn contents x. 2021-04-29T14:00:50Z 2003 terms-of-use Graf, Thomas Ferromagnetic Resonance in Ga<sub>1−x</sub> Mn<sub> x </sub>As Köder, Andreas Wassner, Thomas Waag, Andreas Schoch, Wladimir Stutzmann, Martin Brandt, Martin S.
