Some superconductors can also carry currents of 'spin'

Researchers have shown that certain superconductors—materials that carry electrical current with zero resistance at very low temperatures—can also carry currents of 'spin'. The successful combination of superconductivity ...

Zero field switching (ZFS) effect in a nanomagnetic device

An unexpected phenomenon known as zero field switching (ZFS) could lead to smaller, lower-power memory and computing devices than presently possible. The image shows a layering of platinum (Pt), tungsten (W), and a cobalt-iron-boron ...

Practical spin wave transistor one step closer

University of Groningen physicists have managed to alter the flow of spin waves through a magnet, using only an electrical current. This is a huge step towards the spin transistor that is needed to construct spintronic devices. ...

New research advances spintronics technology

Engineers at the University of California, Riverside, have reported advances in so-called "spintronic" devices that will help lead to a new technology for computing and data storage. They have developed methods to detect ...

Thermal gradients shown to enhance spin transport in graphene

Scientists of the ICN2 Physics and Engineering of Nanodevices Group, led by ICREA Prof. Sergio O. Valenzuela, have contributed to the literature on spin caloritronics with a focus on the effect of thermal gradients on spins ...

Spin current from heat—new material increases efficiency

Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as 'spin currents." ...

Spin dynamics of graphene explained through supercomputing

In a previous study, researchers found evidence to suggest that spin-orbit coupling (SOC) was greater in graphene/transition metal dichalcogenide heterostructures than in regular graphene. In principle, this phenomenon is ...

Spin currents switch at terahertz frequencies

The technology of spintronics is based on the intrinsic spin of electrons. In the medium term, it is set to replace electronics as the basis for technical devices. DESY scientist Lars Bocklage has discovered a new way of ...
