Absence of strong skew scattering in crystals with multi-sheeted Fermi surfaces
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 that a strong skew-scattering mechanism
is absent in such crystals with multi-sheeted Fermi surfaces. Based on this
finding, we conclude on the mutual exclusion of strong intrinsic and
skew-scattering contributions to the considered transport phenomena. It also
allows us to draw general conditions for materials where the anomalous Hall
effect caused by the skew scattering can be achieved giant

Spin and charge currents induced by the spin Hall and anomalous Hall effects upon crossing ferromagnetic/nonmagnetic interfaces
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 structure and a semiclassical description of
electron transport, we compute the skew-scattering contribution to the
transverse spin and charge currents generated by spin and anomalous Hall effect
in a Co/Cu multilayer system doped with Bi impurities. The fact that the
created currents cross the interface between the two materials strongly
influences the efficiency of charge to spin current conversion, as demonstrated
by our results
Re-emergence of enterovirus D68 in Europe after easing the COVID-19 lockdown, September 2021
We report a rapid increase in enterovirus D68 (EV-D68) infections, with 139 cases reported from eight European countries between 31 July and 14 October 2021. This upsurge is in line with the seasonality of EV-D68 and was presumably stimulated by the widespread reopening after COVID-19 lockdown. Most cases were identified in September, but more are to be expected in the coming months. Reinforcement of clinical awareness, diagnostic capacities and surveillance of EV-D68 is urgently needed in Europe

scattering can be achieved
