In nature, free magnetic monopoles remain elusive, and their search, particularly in high-energy physics, is an ongoing challenge. In contrast, construction of the monopole solution (∝r/|r|3 ) is possible by manipulating the electronic and spin textures in Condensed Matter systems, as exemplified by liquid crystals, spin ices, chiral magnets, and others. One strategy to create such ‘emergent monopoles’ is to utilize topological defects or orders that yield quantized Berry phase, the latter amounting to a quantized source or sink of effective gauge field called an ‘emergent magnetic field’. While expected to exist in real systems, the dynamics and novel electromagnetic responses of such emergent monopoles remain largely unexplored. Here we combine small-angle neutron scattering and electrical transport to explore the static and dynamic properties of emergent monopole crystals created by mode-coupling three orthogonal spin helices in single crystalline samples of the chiral-lattice magnet MnGe. In the static limit, the magnetic structure generating the monopole crystal models well both the neutron diffraction data and the averaged static emergent magnetic field that appears as a topological Hall effect. Augmenting the spin fluctuations upon increasing the magnetic field and/or temperature invokes the dynamics of emergent monopole fields, which are captured as diffusive small-angle neutron diffraction patterns, and strong skew scattering that leads to a remarkable sign reversal of the Hall effect. Our approach of combining neutron scattering and transport measurements on single crystal samples of MnGe provides an original exploration of the static and dynamic properties of magnetic monopole crystals, and paves the way for the discovery of further versatile phenomena due to emergent monopoles and their coupling with itinerant electrons.
