Spin devices rev up

Electric currents drive all our electronic devices. The emerging field of spintronics looks to replace electric currents with what are known as spin currents. Researchers from the University of Tokyo have made a breakthrough ...

New quantum system could help design better spintronics

Researchers have created a new testing ground for quantum systems in which they can literally turn certain particle interactions on and off, potentially paving the way for advances in spintronics.

Toward ultrafast spintronics

Electronics have advanced through continuous improvements in microprocessor technology since the 1960s. However, this process of refinement is projected to stall in the near future due to constraints imposed by the laws of ...

Physicists develop concept of new fast non-volatile memory

Using micromagnetic simulation, scientists have found the magnetic parameters and operating modes for the experimental implementation of a fast racetrack memory module that runs on spin current, carrying information via skyrmionium, ...

Graphene bilayer provides efficient transport and control of spins

University of Groningen physicists in collaboration with a theoretical physics group from Universit├Ąt Regensburg have built an optimized bilayer graphene device that displays both long spin lifetimes and electrically controllable ...

Thermal spin currents confirmed in both space and time

Electrons possess their own angular momentum. They turn on their own axis. In physics, the technical term for this property is spin. Such an electron spin is what makes electrons behave as magnets. However, what is special ...

One-way roads for spin currents

Spin is a type of angular momentum intrinsic to particles, roughly speaking as if they were spinning on themselves. Particles can exchange their spin, and in this way spin currents can be formed in a material. Through years ...
