Because each spin of a tetrahedron is also shared with a neighboring tetrahedron, the creation of magnetic monopoles spreads around the crystal like a fans» wave in a stadium, forming monopoles of opposite «magnetic charge.»

Los Alamos National Laboratory staff scientist Cristiano Nisoli explained, «The emergence of magnetic monopoles in spin ice systems is a particular case of what physicists call fractionalization, or deconfinement of quasi-particles that together are seen as comprising the fundamental unit of the system, in this case the north and south poles of a nanomagnet.

Jaubert and Moessner discovered that in terbium titanate (Tb2Ti2O7) spin ice crystals the electric polarization can be big enough to be seen and to stabilize the double layer of magnetic monopoles.

Dr Ludovic Jaubert, group leader in the Professor Nic Shannon's Theory of Quantum Matter Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) together with Prof Roderich Moessner from the Max Planck Institute in Dresden gave a theoretical explanation for the observation of double - layer structure of magnetic monopoles in spin ices.

Even if the existence of magnetic monopoles as elementary particles remains a fundamental open question, condensed - matter physicists have managed to reproduce artificial versions of these exotic particles in rare - earth oxide crystals called «spin ices.»

«These are currently the strongest bounds on the masses of magnetic monopoles that don't rely on assumptions» about how the particles are created, he says.

The existence of hypothetical particles called magnetic monopoles would explain why electric charge comes in integer multiples of the charge of an electron instead of a continuous range of values, Emily Conover reported in «Magnets with a single pole are still giving physicists the slip» (SN: 2/3/18, p. 10).

That estimate depends on another unknown property of monopoles, the strength of their magnetic charge.

But physicists often carry out their calculations in terms of momentum space (also called reciprocal space) rather than ordinary three - dimensional space, Lu explains, and in that framework magnetic monopoles can exist — and their properties match those of Weyl points.

For decades researchers have sought the exception to this rule of fairness and balance: the magnetic monopole.
