There’s even antiferromagnetism—a type of magnetism in which magnetic atoms or ions in a material cancel their magnetism out if they end up next to each other. Atoms in ferromagnets are known to spin in the same direction, and as these atoms spin, so do their electrons. Like a ferromagnet, the electrons did have one spin orientation they preferred, and like an antiferromagnet, there were enough electrons spinning in the opposite direction to cancel out magnetism. With data taking the form of an electron’s spin rather than its charge, it leaves much more space for storage. “The reported results represent the first observation of an electrically-switchable unconventional [opposite direction] magnet,” the researchers .
