Deterministic Field‐Free Switching of Perpendicular Magnetization by Bulk Mirror Symmetry Broken Bi1−xSbx (012) with High Spin Hall Conductivity

open access: yesAdvanced Materials, EarlyView.
Crystal orientation and domain engineering enable bulk mirror symmetry breaking in Bi1−xSbx, resulting in ultralow current‐induced switching of perpendicular magnetization without an external field. By exploiting single‐domain Bi1−xSbx (012), the authors demonstrate an out‐of‐plane spin Hall conductivity of ∼1.12×105ℏ2eΩ−1m−1$ \sim \!1.12 \ensuremath ...

Alloying‐Controlled Tuning of Interfacial Spin‐Orbit Interaction and Magnetic Damping in Crystalline FeCo Thin Films Grown on GaAs(001)

open access: yesAdvanced Materials, EarlyView.
The interfacial spin‐orbit interaction in single‐crystalline Fe1−xCox thin films grown on GaAs(001) can be continuously tuned via alloying. Using spin‐orbit ferromagnetic resonance, the authors find that the interfacial spin‐orbit fields exhibit a nonmonotonic dependence on Co concentration, with a minimum at 20% Co. ABSTRACT The discovery of intrinsic

Gontsy (Ukraine), a settlement with mammoth bone dwellings of the late Upper Palaeolithic in Eastern Europe

open access: yesUISPP Journal, 2018
The upper Palaeolithic settlement of Gontsy (near Lubny, Poltava region, Ukraine) is owned to the Mezinian culture, which occupied the middle and upper Dnieper basin in Eastern Europe during a short period around 15 000-14 000 BP.

Unconventional Biexciton Dynamics in Superradiant Perovskite Quantum Dots Driven by Many‐Body Correlations

open access: yesAdvanced Materials, EarlyView.
Single‐particle spectroscopy and variational quantum Monte Carlo simulations reveal that strong many‐body correlations fundamentally alter biexciton radiative recombination in weakly confined CsPbBr3 quantum dots. Intra‐ and inter‐exciton correlations reverse the conventional lifetime hierarchy, yielding biexcitons with longer radiative lifetimes than ...
