The optical tweezer of ferroelectric skyrmions
X. -G. Wang, L. Chotorlishvili, V. K. Dugaev +7
Strong magneto-electric coupling in two-dimensional helical materials leads to a peculiar type of topologically protected solutions -- skyrmions. Coupling between the net ferroelec…
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…
Conduction of surface electrons in a topological insulator with spatially random magnetization
S. Kudła, A. Dyrdał, V. K. Dugaev +2
Using the Green functions method we study transport properties of surface electrons in topological insulators in the presence of a correlated random exchange field. Such an exchang…
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…
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…
