The field of spintronics, or spin electronics, uses an electron's spin and its magnetic movement to encode instructions and other data. It's sometimes seen as an alternative to electronics, which relies on the electron's charge to encode data. While spintronics has the potential to increase data processing speeds, boost storage capacity and offer increased data resilience, it's been limited because physicists could only move the electrons -- or tiny magnetic particles -- around a single atomic layer. Now, researchers have found a way to move information from magnets in one layer to magnets in another. They hope the discovery will lead to new possibilities for data storage and computing.
