When you make conducting wires thinner, their electrical resistance goes up. This is Ohm’s law, and it is generally right. An important exception is at very low temperatures, where the mobility of electrons increases when wires become so thin that they are effectively two-dimensional. Now, University of Groningen physicists, together with colleagues at Brest University have observed that something similar happens with the conductivity of magnons, spin waves that travel through magnetic insulators, much like a Mexican wave through a stadium.

Antiferromagnetic materials, materials in which atoms are arranged so that all neighboring atoms are anti-parallel (i.e., pointing in the opposite direction) to them, can have several advantageous properties ...
