Researchers at the University of Twente and Beijing Normal University have recently conducted a study investigating the parameter known as spin memory loss (SML) for a variety of different interfaces, using a combination ...
Materials that exhibit topological phases can be classified by their dimensionality, symmetries and topological invariants to form conductive-edge states with peculiar transport and spin properties. For example, the quantum ...
In a recent article published in Science Bulletin, researchers developed an effective organic-cation intercalation strategy to manipulate the interlayer coupling of layered materials, and obtain a class of organic-inorganic ...

Heterostructures with magnetism and topology (geometry) are promising materials to realize exotic topological quantum states. However, such materials are challenging to engineer or synthesize. In a new report on Science Advances, ...
Researchers at Tohoku University have, for the first time, successfully demonstrated a formation and current-induced motion of synthetic antiferromagnetic magnetic skyrmions. The findings are expected to pave the way towards ...

A few months ago, a team of researchers led by Louis Taillefer at the University of Sherbrooke measured the thermal Hall conductivity in several compounds of copper, oxygen and other elements that are also high-temperature ...
Limiting quantum particles to move in one, two, or three dimensions has led to the observation of many striking phenomena. A prime example is the quantization of the Hall conductance measured in 2-D materials in a strong ...
