First-principles study of the structural stability of Mn3Z (Z=Ga, Sn and Ge) Heusler compounds

Delin Zhang, Binghai Yan, Shu-Chun Wu +4

We investigate the structural stability and magnetic properties of cubic, tetragonal and hexagonal phases of Mn3Z (Z=Ga, Sn and Ge) Heusler compounds using first-principles density…

Physical properties and band structure of reactive molecular beam epitaxy grown oxygen engineered HfO

Erwin Hildebrandt, Jose Kurian, Lambert Alff

We have conducted a detailed thin film growth structure of oxygen engineered monoclinic HfO grown by reactive molecular beam epitaxy (MBE). The oxidation conditions indu…

On the non-uniform motion of dislocations: The retarded elastic fields, the retarded dislocation tensor potentials and the Liénard-Wiechert tensor potentials

Markus Lazar

The purpose of this paper is the fundamental theory of the non-uniform motion of dislocations in two and three space-dimensions. We investigate the non-uniform motion of an arbitra…

Realization of spin gapless semiconductors: the Heusler compound Mn2CoAl

Siham Ouardi, Gerhard H. Fecher, Jürgen Kübler +1

Recent studies have reported an interesting class of semiconductor materials that bridge the gap between semiconductors and halfmetallic ferromagnets. These materials, called spin…

Topological phase transitions in bulk

Stanislav Chadov, Janos Kiss, Jürgen Kübler +1

We consider the analogy between the topological phase transition which occurs as a function of spatial coordinate on a surface of a non-trivial insulator, and the one which occurs…

The fundamentals of non-singular dislocations in the theory of gradient elasticity: dislocation loops and straight dislocations

Markus Lazar

The fundamental problem of non-singular dislocations in the framework of the theory of gradient elasticity is presented in this work. Gradient elasticity of Helmholtz type and bi-H…
