Spin Hall Magnetoresistance in Metallic Bilayers with In-plane Magnetized Ferromagnets
Łukasz Karwacki, Krzysztof Grochot, Stanisław Łazarski +6
We revisit the theory and experiment on spin Hall magnetoresistance (SMR) in bilayers consisting of a heavy metal (H) coupled to in-plane magnetized ferromagnetic metal (F), and de…
Determination of spin Hall angle in heavy metal/CoFeB-based heterostructures with interfacial spin-orbit fields
Witold Skowroński, Łukasz Karwacki, Sławomir Ziętek +7
Magnetization dynamics in W/CoFeB, CoFeB/Pt and W/CoFeB/Pt multilayers was investigated using spin-orbit-torque ferromagnetic resonance (SOT-FMR) technique. An analytical model bas…
Thermoelectric properties of a quantum dot coupled to magnetic leads by Rashba spin-orbit interaction
Łukasz Karwacki, Józef Barnaś
We consider a single-level quantum dot coupled to two leads which are ferromagnetic in general. Apart from tunneling processes conserving electron spin, we also include processes a…
Current-induced spin polarization in isotropic k-cubed Rashba model: Theoretical study for p-doped semiconductor heterostructures and perovskite oxides interfaces
L. Karwacki, A. Dyrdal, J. Berakdar +1
Using the Matsubara Green's function formalism we calculate the temperature dependence of the nonequilibrium spin polarization induced by an external electric field in the presence…
Magnon cotunneling through a quantum dot
Łukasz Karwacki
I consider a single-level quantum dot coupled to two reservoirs of spin waves (magnons). Such systems have been studied recently from the point of view of possible coupling between…
Magnon transport through a quantum dot: Conversion to electronic spin and charge currents
Łukasz Karwacki, Piotr Trocha, Józef Barnaś
We consider a single-level quantum dot coupled to magnetic insulators (magnonic reservoirs) and magnetic metals (electronic reservoirs). The whole system is in an external magnetic…
