This review summarizes recent first-principles investigations of the electronic structure and
magnetism of dilute magnetic semiconductors (DMSs), which are interesting for applications …

The body of research on (III, Mn) V diluted magnetic semiconductors (DMSs) initiated during
the 1990s has concentrated on three major fronts:(i) the microscopic origins and …

The purpose of this book is to provide a theoretical foundation and an understanding of
atomistic spin-dynamics (ASD), and to give examples of where the atomistic Landau-Lifshitz …

The search for ferromagnetism above room temperature in dilute magnetic semiconductors
has been intense in recent years. We report the first observations of ferromagnetism above …

Effective pair exchange interactions between Mn atoms in III-V and group-IV diluted
magnetic semiconductors are determined from a two-step first-principles procedure. In the …

We present a combined theoretical and experimental study of the ferromagnetic
semiconductor (G a, M n) A s which explains the remarkably large changes observed on low …

We have used positron annihilation spectroscopy to study the introduction and recovery of
point defects in electron-irradiated n-type ZnO. The irradiation (E el= 2 MeV, fluence 6× 10 …

We demonstrate that the magnetic properties of diluted magnetic semiconductors are
dominated by short ranged interatomic exchange interactions that have a strong directional …

Results of extensive density-functional studies provide direct evidence that Cr atoms in Cr∶
GaN have a strong tendency to form embedded clusters, occupying Ga sites. Significantly …

The effect of low-temperature annealing on (Ga, Mn) As trilayer structures was investigated.
The annealing was done at 250-280 C in air and the temperature dependence of the …
