For Tg around 200 °C, high-quality single crystal films were obtained without the Ag buffer layer. For Tg ≦ 100 °C, a defect structure was observed in the iron layer. However, the addition of an ultrathin Ag buffer layer between GaAs and Fe has the desirable effects of eliminating the defect structure and significantly enhancing the FMR absorption. |
