Germany produces magnetic monopoles inside solid matter

In a recent report from the US Daily Science website, German scientists have successfully created an artificial magnetic monopole by combining tiny magnetic vortices—small magnetic tips found on the surface of a magnet. This artificial monopole exhibits properties identical to those theoretically predicted for real magnetic monopoles. Scientists believe that these artificial monopoles could one day be used in advanced computer components, beyond just their significance in fundamental research. The study was published in the prestigious journal *Science*.
A magnetic monopole is a hypothetical particle that possesses only a single magnetic pole—either a north or south pole—unlike regular magnets, which always have both poles. The concept was first proposed in 1931 by British physicist Paul Dirac, who theorized that if electric charges exist, then magnetic charges must also exist. Since then, researchers have been searching for evidence of magnetic monopoles in nature, but so far, none have been discovered.
Now, a team of scientists from the University of Cologne, Ludwig Maximilian University in Munich, and the University of Dresden has created an artificial magnetic monopole within a solid material, demonstrating behavior that closely matches the theoretical predictions of a true magnetic monopole.
Over the past few years, the research group studied materials that exhibit magneto-rotations—structures that influence electron movement similarly to a magnetic field. They described these effects using artificial magnetic fields and measured them in the same way as real magnetic fields.
To explore what happens when these magneto-rotations are disrupted, the team used a magnetic microscope to observe the magnetization patterns. They found that when the rotations were destroyed, magnetic fluxes merged together in a clear and observable way.
But what exactly was happening inside the material? Neutron scattering experiments revealed a similar process, although no isolated magnetic pole was directly observed. Computer simulations later confirmed that the magnetic rotations seen at the surface also occurred deep within the material.
Each magnetic vortex generates an artificial magnetic field, and when two of them meet, they create an artificial magnetic monopole at the point of intersection. According to Professor Rosch from the University of Cologne, “This means there must be an artificial magnetic monopole at that location. When two magnetic vortices merge, an artificial monopole appears on its surface, and its behavior aligns perfectly with the theoretical predictions. That’s truly fascinating.â€
Beyond academic curiosity, artificial magnetic monopoles may hold promise for future technologies. Many research groups are investigating whether magnetic spin structures can be used in computing devices. If so, controlling the creation and destruction of these spins would become essential, and magnetic monopoles could play a key role in this development.
