Keep cool: Researchers develop magnetic cooling cycle

As a result of climate change, population growth, and rising expectations regarding quality of life, energy requirements for cooling processes are growing much faster worldwide than for heating. Another problem that besets ...

Magnetism has the pull to transform our digital lives

Digital memory and security could be transformed according to new research, which has for the first time showed that antiferromagnets can be easily controlled and read by switching the direction of ordinary electrical currents ...

Chemical 'pressure' tuning magnetic properties

Unusual, tiny vortexes spinning on the surface of certain magnets could offer a way to reduce the energy demands of computers. Controlling the vortexes is key. Scientists found that chemical substitution in a well-studied ...

Controlling spin for memory storage

Tohoku University researchers have developed a computational simulation that shows that using ultrafast laser pulses to excite electrons in a magnetic material switches them into a transient non-magnetic state. This could ...
