![]() | Scarpulla, Michael | Ferromagnetic Ga1-xMnxAs produced by ion implantation and pulsed-laser melting | We demonstrate the formation of ferromagnetic Ga1-xMnxAs films by Mn ion implantation into GaAs followed by pulsed-laser melting. Irradiation with a single excimer laser pulse results in the epitaxial regrowth of the implanted layer with Mn substitutional fraction up to 80% and effective Curie tempe... | Gallium arsenide; Ferromagnetic semiconductors; Remanent magnetization | 2003 |
