Antiferromagnets are suitable for dissipationless nanoelectronics, contrary to current theories

Sometimes combinations of different things produce effects that no one expects, such as when completely new properties appear that the two combined parts do not have on their own. Dr. Libor Ċ mejkal from Johannes Gutenberg ...
