Scientists from TU Delft (The Netherlands) have observed quantum spin currents in graphene for the first time without using ...

A smart magnetic stir bar puts a new spin on a classic research tool (ACS Sens. 2020, DOI: 10.1021/acssensors.0c00720). In addition to mixing reagents, it tracks multiple physical properties ...

Magnetic stirring bars are the coolest piece of equipment you’ll see in a high-school chemistry lab. They’re a great way for agitating a solution without having to stand there manually and do ...

Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with ...

Each caesium atom is equivalent to a small bar magnet, which is affected by external magnetic fields. The atoms and thus the magnetic field are picked up using laser light.

The total area of the Hall bar is 500 × 500 µm2, while the effective sensing area is 20 × 20 µm2; (b) Hall resistance vs. external magnetic field at various temperatures (the inset shows the ...

Lodestone, a naturally-occurring iron oxide, was the first persistently magnetic material known to humans. The Han Chinese used it for divining boards 2,200 years ago; ancient Greeks puzzled over ...

Magnetic measurements in household and work environments demonstrate measurements below 0.1mT, or 1G, at distances greater than 16cm, or 6.3in, from various appliances and tools.

The scientists now, for the first time, have experimentally implemented a so-called quantum resistance standard that can operate without an externally applied magnetic field.

The job of a catalyst is to ultimately speed up reactions, which could reduce an hour-long process into several minutes. It has recently been shown that using external magnetic fields to modulate ...
