- Abstract
- The p-type InP:Be/Mn/InMnP:Be triple epilayers were prepared using MBE to increase Tc (>300 K) by preventing MnO2. After milling 1-3 nm of epilayers thickness from the top surface, the transmission electron microscopy (TEM) and X-ray diffraction (XRD) revealed no MnO2 and precipitates, and TEM and XRD results coincide with results of ferromagnetism. The enhanced ferromagnetic transition at >300 K corresponds to InMnP:Be. The increased ferromagnetic coupling without MnO2 is considered to originate from the increased p-d hybridation. These results demonstrate that InP-based ferromagnetic semiconductor layers having enhanced ferromagnetism can be formed by above process. (C) 2014 Elsevier B.V. All rights
