Giant superconducting proximity effect on spintronic anisotropy
Krzysztof P. Wójcik, Maciej Misiorny, Ireneusz Weymann
We investigate theoretically the interplay of proximity effects due to the presence of a superconductor and normal ferromagnetic leads on the formation of the spintronic quadrupola…
Nonlocal Andreev Reflections as a Source of Spin Exchange and Kondo Screening
Krzysztof P. Wójcik, Ireneusz Weymann
We report on a novel exchange mechanism, mediating the Kondo screening, in a correlated double quantum dot structure in the proximity of superconductor, stemming from nonlocal Andr…
Splitting efficiency and interference effects in a Cooper pair splitter based on a triple quantum dot with ferromagnetic contacts
K. Bocian, W. Rudzinski, I. Weymann
We theoretically study the spin-resolved subgap transport properties of a Cooper pair splitter based on a triple quantum dot attached to superconducting and ferromagnetic leads. Us…
Interplay of the Kondo effect with the induced pairing in electronic and caloric properties of T-shaped double quantum dots
Krzysztof P. Wójcik, Ireneusz Weymann
We examine the influence of the superconducting proximity effect on the transport properties of a T-shaped double quantum dot strongly coupled to two normal, nonmagnetic or ferroma…
Dark states in spin-polarized transport through triple quantum dot molecules
Kacper Wrześniewski, Ireneusz Weymann
We study the spin-polarized transport through a triple quantum dot molecule weakly coupled to ferromagnetic leads. The analysis is performed by means of the real-time diagrammatic…
Manipulating spins of magnetic molecules: Hysteretic behavior with respect to bias voltage
Anna Płomińska, Maciej Misiorny, Ireneusz Weymann
Formation of a magnetic hysteresis loop with respect to a bias voltage is investigated theoretically in a spin-valve device based on a single magnetic molecule. We consider a devic…
