A group of U.S.-based physicists has presented experimental evidence suggesting that electricity can be generated from the rotational energy of the Earth, using a custom-designed device interacting ...

Spintronics, an emerging field of technology, exploits the spin of electrons rather than their charge to process and store information. Spintronics could lead to faster, more power-efficient computers ...

Scientists have discovered that electron spin loss, long considered waste, can instead drive magnetization switching in spintronic devices, boosting efficiency by up to three times. The scalable, ...

Researchers at the University of Minnesota Twin Cities have made a promising breakthrough in memory technology by using a nickel-tungsten alloy called Ni₄W. This material shows powerful magnetic ...

(Left) A conventional structure that runs a current through the outside of a magnet to generate spins and drive them into the magnet. Some of the spins leak out as they travel, and this spin loss ...

(a) A sketch of the spin-valve effect in bulk kagome helimagnet. (b) MFM images of TmMn6Sn6 under magnetic field. (c) The asymmetric magnetoresistance for electric current along the helical axis of ...
