Artist's image showing robot arms controlling a group of spins (represented by an array of red arrows all pointing up) that are sandwiched between two layers of CrS material (represented by ball-and-stick models). A blue lightning-like line in the middle represents electric field control
Altermagnetics: Electrical current flowing in an altermagnetic bilayer CrS can become spin-polarized using an external electric field, thus paving a way towards all-electrical spintronic devices for future computing technology. (Courtesy: SUTD)
A new all-electrical way of controlling spin-polarized currents has been developed by researchers at
