Unveiling the secrets of liquid iron under extreme conditions

Two new innovative methods describe how to measure the electrical resistivity of liquid iron—such as that found in planetary cores—at extremely high pressures and temperatures. Prior to this, there were no experimental ...

Examining domain walls in magnetic nanowires

Magnetic domains walls are known to be a source of electrical resistance due to the difficulty for transport electron spins to follow their magnetic texture. This phenomenon holds potential for utilization in spintronic devices, ...

Building better superconductors with palladium

It is one of the most exciting races in modern physics: How can we produce the best superconductors that remain superconducting even at the highest possible temperatures and ambient pressure? In recent years, a new era of ...

The quantum spin liquid that isn't one

For two decades, it was believed that a possible quantum spin liquid was discovered in a synthetically produced material. In this case, it would not follow the laws of classical physics even on a macroscopic level, but rather ...

Closing in on next-generation atom-thick photonic devices

From microscopes and cameras to night vision devices and optical fiber communications, photodetectors have a wide array of applications. Photodetectors capture and convert light into electrical signals but are often limited ...
