| Title |
Carrier concentration dependencies of magnetization & transport in Ga1-xMnxAs1-yTey |
| Date |
2005 |
| Description |
We have investigated the transport and magnetization characteristics of Ga1-xMnxAs intentionally compensated with shallow Te donors. Using ion implantation followed by pulsed-laser melting, we vary the Te compensation and drive the system through a metal-insulator transition (MIT). This MIT is associated with enhanced low-temperature magnetization and an evolution from concave to convex temperature-dependent magnetization. |
