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 Šmejkal from Johannes Gutenberg University Mainz (JGU) found such an unexpected property: He combined antiferromagnetic substances with non-magnetic atoms and found that, contrary to the current doctrine, a Hall current occurs—which is not the case with either antiferromagnetic or non-magnetic substances individually.
This could offer completely new potential for nanoelectronics. On the one hand, these material combinations occur very frequently in nature. Therefore, this
