Researchers at the University of Basel in collaboration with colleagues from Pisa have developed a new concept that uses electron spin to switch an electrical current. In addition to fundamental research, such spin valves are also the key elements in spintronics—a type of electronics that exploits the spin instead of the charge of electrons. The results were published in the scientific journal Communications Physics.
