Substrate-Controlled Magnetism: Fe nanowires on vicinal Cu surfaces
Daniel Hashemi, Michael Waters, Valeriy S. Stepanyuk +2
Here we present a novel approach to control magnetic interactions in atomic-scale nanowires. Our ab initio calculations demonstrate the possibility to tune magnetic properties of F…
Fast spin dynamics in hexagonal arrays of Fe atoms on metallic surface
Tamene R. Dasa, Valeri S. Stepanyuk
Understanding the nature of magnetic interactions in ultra-small magnetic ensembles and their intrinsic properties is vital to uncover the dynamics therein. In this study we reveal…
Gate control of spin-polarized conductance in alloyed transition metal nano-contacts
Ilia N. Sivkov, Oleg O. Brovko, Ivan Rungger +1
To date, endeavors in nanoscale spintronics are dominated by the use of single-electron or single-spin transistors having at their heart a semiconductor, metallic or molecular quan…
Direct surface charging and alkali-metal doping for tuning the interlayer magnetic order in planar nanostructures
Tamene R. Dasa, Valeri S. Stepanyuk
The continuous reduction of magnetic units to ultra small length scales inspires efforts to look for a suitable means of controlling magnetic states. In this study we show two surf…
Ultrafast quantum spin-state switching in the Co-octaethylporphyrin molecular magnet with a terahertz pulsed magnetic field
Oleg V. Farberovich, Victoria L. Mazalova, Valeri S. Stepanyuk
Molecular spin crossover switches are the objects of intense theoretical and experimental studies in recent years. This interest is due to the fact that these systems allow one to…
Ferromagnetism of Pd(001) substrate induced by Antiferromagnetic CoO
S. K. Saha, V. S. Stepanyuk, J. Kirschner
Our first-principles study has revealed unexpected spin polarization of the Pd(001) substrate in contact with antiferromagnetic CoO overlayers. We give an evidence that the ferroma…
