The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Researchers have demonstrated that the direction of the spin-polarized current can be restricted to only one direction in a single-atom layer of a thallium-lead alloys when irradiated at room ...

An international team has succeeded at BESSY II to elucidate how ultrafast spin-polarized current pulses can be characterized by measuring the ultrafast demagnetization in a magnetic layer system ...

Osaka, Japan – Despite their identical composition, molecules that are mirror images can interact differently with light and electrical current depending on their “handedness”, which is called ...

What is a Quantum Spin Hall Insulator? A quantum spin Hall insulator (QSHI) is a novel state of matter that exhibits unique electronic properties. It is a type of topological insulator, which is a ...

When circular polarized light is irradiated onto a thallium lead alloy, the majority “up spins” of electrons flow in the right direction (spin-polarized current). Researchers Ibuki Taniuchi, Ryota ...
