Spectral analysis of topological defects in an artificial spin-ice lattice
Sebastian Gliga, Attila Kákay, Riccardo Hertel +1
Arrays of suitably patterned and arranged magnetic elements may display artificial spin-ice structures with topological defects in the magnetization, such as Dirac monopoles and Di…
Analysis of the Kondo effect in ferromagnetic atomic-sized contacts
M. Reyes Calvo, David Jacob, Carlos Untiedt
Atomic contacts made of ferromagnetic metals present zero-bias anomalies in the differential conductance due to the Kondo effect. These systems provide a unique opportunity to perf…
Relativistic peculiarities at stepped surfaces: surprising energetics and unexpected diffusion patterns
Oleg O. Brovko, Nikolay N. Negulyaev, Valeri S. Stepanyuk
We revive intriguing, yet still unexplained, experimental results of Ehrlich and co-workers [ Phys. Rev. Lett. 77 1334 (1996); Phys. Rev. Lett. 67 2509 (1991)] who have observed, t…
Confined bulk states as a long-range sensor for impurities and a transfer channel for quantum information
Oleg O. Brovko, Pavel A. Ignatiev, Valeri S. Stepanyuk
We show that confinement of bulk electrons can be observed at low-dimensional surface structures and can serve as a long-range sensor for the magnetism and electronic properties of…
