Controlling magnetization dynamics with a femtosecond laser is attracting interest both in fundamental science and in industry because of the potential to achieve magnetic switching at ever faster ...

Electrons inherently carry both spin and orbital angular momentum (i.e., properties that help to understand the rotating motions and behavior of particles). While some physicists and engineers have ...

Spintronics -- based on the principles of electron charge and magnetic spin -- goes beyond the limits of conventional electronics. However, spintronic devices are yet to see advances, because ...

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is ...

Led by researchers at Lancaster University, the international team showed that subtle electronic effects can greatly amplify how magnets respond to ultrafast light. The findings deepen scientific ...

The reliability of data storage and writing speed in advanced magnetic devices depend on drastic, complex changes in microscopic magnetic domain structures. However, it is extremely challenging to ...

Like sailors and spelunkers, physicists know the power of a sturdy knot. Some physicists have tied their hopes for a new generation of data storage to minuscule knotlike structures called skyrmions, ...

An international team of researchers led by Lancaster University has discovered a highly efficient mechanism for shaking magnets using very short light pulses, shorter than a trillionth of a second.

Birds are the best-known example of creatures able to sense magnetic fields and to use them for orientation and navigation. Less well known are the magneto-sensing abilities of American cockroaches, ...

Spin flips: physicists have magnetized water by spinning it at high speeds. (Courtesy: Shutterstock/Inna Bigun) Physicists in the US have shown that rotating matter at high speeds can magnetize atomic ...
