| Research Abstract |
Ferromagnetic semiconductors have been recently attracted world wide scientific and technological interest because of possible application in spintronic devices. Two-major criteria such as room-temperature ferromagnetism and process compatibility for semiconductor spintronic materials are required from a practical point of view. Mn-doped ZnSnAs2 thin films were grown on InP substrates by molecular beam epitaxy (MBE). Heteroepitaxial growth of InGaAs and InAlAs layers on ZnSnAs2 / InP using low-temperature MBE is investigated in order to produce InP-based spintronic devices. We have successfully grown MnAs/ZnSnAs2/ZnSnAs2:Mn trilayer heterostructures on InP(001) substrates. The current-in-plane giant magnetoresistance (CIP-GMR) was clearly observed in magnetoresistance measurements in current-in-plane geometry.
