Over the past two decades, the research of (Ga, Mn) As has led to a deeper understanding
of relativistic spin-dependent phenomena in magnetic systems. It has also led to discoveries …

Weak antilocalization (WAL) is expected whenever strong spin-orbit coupling or scattering
comes into play. Spin-orbit coupling in the bulk states of a topological insulator is very …

Electronic states in disordered conductors on the verge of localization are predicted to
exhibit critical spatial characteristics indicative of the proximity to a metal-insulator phase …

Emerging for future spintronic/electronic applications, magnetic semiconductors have
stimulated intense interest due to their promises for new functionalities and device concepts …

HgTe quantum wells and surfaces of three-dimensional topological insulators support Dirac
fermions with a single-valley band dispersion. In the presence of disorder they experience …

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 …

Recently, the hexagonal compound SrAgBi has been theoretically predicted to host linearly
dispersing type-II and nonlinearly dispersing type-IV Dirac fermions near the Fermi level …

While the support for the existence of a Mn-derived impurity band in the diluted magnetic
semiconductor Ga 1− x Mn x As has recently increased, a detailed quantitative analysis of its …

We report the observation of large tunable positive magnetoresistance (MR) effects in
magnetic lanthanide half-Heusler compounds RPtBi (R= Tb, Dy, Ho, Er, and Tm). The value …

Quantum coherence of electrons can produce striking behaviors in mesoscopic conductors.
Although magnetic order can also strongly affect transport, the combination of coherence …
