Background and Purpose
Recent developments in the physics of spin ice have identified emergent magnetic monopole excitations that couple to laboratory magnetic fields. Since 2008 there have been many high impact publications in this area including several in Science or Nature group journals. The field is rapidly advancing, with many new ideas being advanced, and new avenues explored. In particular, currents of magnetic monopoles in spin ice are closely analogous to protonic currents in water ice, a solid electrolyte. Hence there is a strong overlap with ice physics and electrochemistry, which has introduced new concepts into magnetism that that from a traditional viewpoint seem very alien. The interchange of ideas between magnetism, ice physics and electrochemistry promises exciting advances in all these areas, yet it is important that scientists engage in discussion and the exchange of information to prevent progress from stagnating.
