Research Abstract |
We have studied and established the fabrication technologies of ferromagnet/semiconductor hybrid materials; 1) III-V-based ferromagnetic semiconductors which contains sizable amount of magnetic ions (Mn) and their heterostructures, and 2) ferromagnetic-metal/III-V semiconductor heterostructures, by using molecular beam epitaxy. Furthermore, we investigated their structural, electronic, optical, and magnetic properties, and realized unique and useful properties that cannot be seen in the conventional semiconductor or magnetic materials alone. These properties we found are shown to be applicable to some future "spintronic" devices.
