Electrically controlled spin-transistor operation in helical magnetic field
P. Wójcik, J. Adamowski
A proposal of electrically controlled spin transistor in helical magnetic field is presented. In the proposed device, the transistor action is driven by the Landau-Zener transition…
Tunneling conductance in half-metal/conical magnet/superconductor junctions in the adiabatic and non-adiabatic regime: self-consistent calculations
P. Wójcik, B. Rzeszotarski, M. Zegrodnik
The tunneling conductance in the half-metal/conical magnet/superconductor (HM/CM/SC) is investigated by the use of the combined Blonder-Tinkham-Klapwijk (BTK) formalism and the Bog…
Resonant Landau-Zener transitions in helical magnetic fields
P. Wojcik, J. Adamowski, M. Woloszyn +1
The spin-dependent electron transport has been studied in magnetic semiconductor waveguides (nanowires) in the helical magnetic field. We have shown that -- apart from the known co…
Non-ballistic spin separator based on Y-shaped nanostructure with a quantum point contact
P. Wojcik, M. Woloszyn, B. J. Spisak +1
A proposal of a spin separator based on the spin Zeeman effect in Y-shaped nanostructure with a quantum point contact is presented. Our calculations show that the appropriate tunin…
Spin transistor operation driven by the Rashba spin-orbit coupling in the gated nanowire
P. Wójcik, J. Adamowski, B. J. Spisak +1
The theoretical description has been proposed for the operation of the spin transistor in the gate-controlled InAs nanowire. The calculated current-voltage characteristics show tha…
Spin filter effect at room temperature in GaN/GaMnN ferromagnetic resonant tunneling diode
P. Wójcik, J. Adamowski, M. Wołoszyn +1
We have investigated the spin current polarization without the external magnetic field in the resonant tunneling diode with the emitter and quantum well layers made from the ferrom…
