What is the News?

A group of scientists has used computer simulations to design a new type of quantum material. This material has a unique property called Rashba splitting, which is important for spintronic devices. 

What is Spintronics?

Spintronics is one of the emerging fields for the next-generation nanoelectronic devices to reduce their power consumption and to increase their memory and processing capabilities. 

Such devices take advantage of electron spin, a quantum property of electrons, to achieve higher performance.

Some of the examples of spintronic devices are spin transistors, spin diodes, and spin filters.

What have the researchers developed?

Researchers have created composite 2-D quantum materials showing two different quantum properties, Rashba effect  (a momentum-dependent splitting of spin bands) and nonlinear anomalous Hall effect (arising from anomalous velocity of the electrons) in the same material.

The designed material could help overcome limitations in current spintronic devices and lead to better performance in areas like quantum computing and communication.
