Skyrmionic Spin Structures in Layered Fe5GeTe2 Up To Room Temperature
Maurice Schmitt, Thibaud Denneulin, András Kovács +12
The role of the crystal lattice, temperature and magnetic field for the spin structure formation in the 2D van der Waals magnet Fe5GeTe2 is a key open question. Using Lorentz trans…
Magnetic anisotropy in Fe/U and Ni/U bilayers
E. R. Gilroy, M. -H. Wu, M. Gradhand +2
Magnetometry measurements of Fe/U and Ni/U bilayer systems reveal a non-monotonic dependence of the magnetic anisotropy for U thicknesses in the range 0 nm - 8 nm, with the Fe/U bi…
Interfacial mechanism in the anomalous Hall effect of Co/BiO bilayers
Edurne Sagasta, Juan Borge, Luis Esteban +5
Oxide interfaces are a source of spin-orbit coupling which can lead to novel spin-to-charge conversion effects. In this work the contribution of the BiO interface to the an…
Relation between spin Hall effect and anomalous Hall effect in 3 ferromagnetic metals
Yasutomo Omori, Edurne Sagasta, Yasuhiro Niimi +4
We study the mechanisms of the spin Hall effect (SHE) and anomalous Hall effect (AHE) in 3 ferromagnetic metals (Fe, Co, permalloy (NiFe; Py), and Ni) by varying t…
Insights into spin and charge currents crossing ferromagnetic/nonmagnetic interfaces induced by spin and anomalous Hall effect
Albert Hönemann, Christian Herschbach, Dmitry V. Fedorov +2
We start closing a gap in the comparison of experimental and theoretical data associated with the spin Hall effect. Based on a first-principles characterization of electronic struc…
Absence of strong skew scattering in crystals with multi-sheeted Fermi surfaces
Albert Hönemann, Christian Herschbach, Dmitry V. Fedorov +2
We consider an extrinsic contribution to the anomalous and spin Hall effect in dilute alloys based on Fe, Co, Ni, and Pt hosts with different substitutional impurities. It is shown…
Unveiling the mechanisms of the spin Hall effect in Ta
Edurne Sagasta, Yasutomo Omori, Saül Vélez +7
Spin-to-charge current interconversions are widely exploited for the generation and detection of pure spin currents and are key ingredients for future spintronic devices including…
Seebeck Effect in Nanomagnets
Dmitry V. Fedorov, Martin Gradhand, Katarina Tauber +2
We present a theory of the Seebeck effect in nanomagnets with dimensions smaller than the spin diffusion length, showing that the spin accumulation generated by a temperature gradi…
Tuning the spin Hall effect of Pt from the moderately dirty to the superclean regime
Edurne Sagasta, Yasutomo Omori, Miren Isasa +5
We systematically measure and analyze the spin diffusion length and the spin Hall effect in Pt with a wide range of conductivities using the spin absorption method in lateral spin…
Temperature dependence of spin diffusion length and spin Hall angle in Au and Pt
Miren Isasa, Estitxu Villamor, Luis E. Hueso +2
We have studied the spin transport and the spin Hall effect as a function of temperature for platinum (Pt) and gold (Au) in lateral spin valve structures. First, by using the spin…
Colossal Spin Hall Effect in Ultrathin Metallic Films
Christian Herschbach, Dmitry V. Fedorov, Martin Gradhand +1
We predict spin Hall angles up to 80% for ultrathin noble metal films with substitutional Bi impurities. The colossal spin Hall effect is caused by enhancement of the spin Hall con…
Insight into the skew-scattering mechanism of the spin Hall effect: potential scattering versus spin-orbit scattering
Christian Herschbach, Dmitry V. Fedorov, Ingrid Mertig +4
We present a detailed analysis of the skew-scattering contribution to the spin Hall conductivity using an extended version of the resonant scattering model of Fert and Levy [Phys.…
On the origin of the giant SHE in Cu(Bi) alloys
Dmitry V. Fedorov, Christian Herschbach, Sergey Ostanin +5
Two years after the prediction of a giant spin Hall effect for the dilute Cu(Bi) alloy [Gradhand et al., Phys. Rev. B 81, 245109 (2010)], a comparably strong effect was measured in…
On calculating the Berry curvature of Bloch electrons using the KKR method
M. Gradhand, D. V. Fedorov, F. Pientka +3
We propose and implement a particularly effective method for calculating the Berry curvature arising from adiabatic evolution of Bloch states in wave vector k space. The method exp…
