Lighting up spintronics with re-writeable circuits
Researchers at the University of California Berkeley (UCB) and the City College of New York (CCNY) have developed a way of controlling the spin of a nucleus that could one day allow us to make rewritable spintronics circuits with light.According to Professor Jeremy Reimer, UCB professor of chemical and biomolecular engineering and the study co-author, the major drawback of existing chips is their permanence: "Once the chip is printed, it can only be used one way," he said.
