Single-atomic metal layer reveals unexpected spin-polarized current control by light
When circularly polarized light is applied to a thallium-lead alloy, the majority of the electrons “up-spin” and flow in the correct direction (spin-polarized current). Credit: Taniuchi et al. 2025 Researchers at the University of Tokyo have demonstrated that the direction of spin-polarized current is restricted to only one direction in a single atomic layer of a thallium-lead alloy when irradiated…

‘Twisted’ 2D materials exhibit unexpected electronic behavior that defies theoretical predictions
This photo shows first author Giovanna Feraco (Zernike Institute for Advanced Materials, University of Groningen, Netherlands) operating an ultra-high vacuum (UHV) system at the synchrotron facility. Credit: University of Groningen In search of new materials that will enable more efficient electronics, scientists are researching so-called 2D materials. These are sheets just one atom thick and can have all sorts of…

New study reveals unexpected interaction between Mars and the solar wind
Main regions and boundaries of the degenerate magnetosphere and the near-Mars environment (near-parallel IMF). Credit: Nature (2024). DOI: 10.1038/s41586-024-07959-z Scientists from the Swedish Institute of Astrophysics (IRF) in Kiruna and Umeå University have discovered that under certain conditions the induced magnetosphere of Mars can degrade, their findings are published in a new study in the journal Nature. An induced magnetosphere…
