Large intrinsic anomalous Hall effect in SrIrO3 induced by magnetic proximity effect [PDF]

Nature Communications, 2021
The anomalous Hall effect (AHE) occurs in ferromagnets caused by intrinsic and extrinsic mechanisms. Here, Yoo et al. report large anomalous Hall conductivity and Hall angle at the interface between a ferromagnet La0.7Sr0.3MnO3 and a semimetallic SrIrO3,

Superconducting imprint of magnetic textures in ferromagnets with perpendicular magnetic anisotropy [PDF]

Scientific Reports, 2021
Research on proximity effects in superconductor/ferromagnetic hybrids has most often focused on how superconducting properties are affected—and can be controlled—by the effects of the ferromagnet’s exchange or magnetic fringe fields. The opposite, namely

Vulnerability of peri‑urban and residential areas to landscape fires in Greece: Evidence by wildland-urban interface data [PDF]

Data in Brief, 2020
We provide a map of wildland urban interface (WUI) areas at national scale in Greece, using as primary data the Corine Land Cover (CLC) 2018 product. The WUI areas distribution in Greece is calculated for all the regional units of the county.
