Combining semiconducting and ferromagnetic properties, dilute ferromagnetic
semiconductors (DFS) have been under intensive investigation for more than two decades …

The self-assembled nanostructured materials described in this book offer a number of
advantages over conventional material technologies in a wide range of sectors. World …

Diluted ferromagnetic semiconductors (FMS) are in the focus of intense research due to their
potential applications in spintronics and their striking new physical properties. So far Mn …

Room temperature ferromagnetism of Mn+-implanted Si nanowires (NWs) has been
discovered. The saturation magnetization was found to increase with the Mn concentration …

By using ab initio electronic structure calculations within density functional theory, we study
the structural, electronic, and magnetic properties of Si doped with a transition metal …

A possible mechanism for high-temperature ferromagnetic order in Si: Mn alloys is
proposed. These materials, which are semiconducting or metallic, depending on the Mn …

In this work, silicon-germanium (SiGe) thin films are epitaxially grown on Ge substrates by
ultra-high vacuum chemical vapor deposition and then doped with Mn element by ion …

Mn-doped polycrystalline SiGe thin films are fabricated by radio frequency magnetron
sputtering and subsequent rapid thermal annealing. Structural characterizations show that …

Transition metals such as Mn generally have large local moments in covalent
semiconductors due to their partially filled d shells. However, Mn magnetization in group-IV …
