Efforts to find the magnetic monopole in real space have been made in cosmic rays and in particle accelerators, but there has not yet been any firm evidence for its existence because of its very heavy mass, ∼1016 giga–electron volts. We show that the magnetic monopole can appear in the crystal momentum space of solids in the accessible low-energy region (∼0.1 to 1 electron volts) in the context of the anomalous Hall effect. We report experimental results together with first-principles… Expand

A few examples recently studied related to these issues with some new results on skyrmion formation are discussed, including the Hall effect produced by the spontaneous magnetization combined with the relativistic spin–orbit interaction. Expand
Anomalous Hall effect in a two-dimensional electron gas with spin-orbit interaction
We discuss the mechanism of anomalous Hall effect related to the contribution of electron states below the Fermi surface induced by the Berry phase in momentum space. Our main calculations are madeExpand
Magnetic monopoles in spin ice
This work proposes that magnetic monopoles emerge in a class of exotic magnets known collectively as spin ice: the dipole moment of the underlying electronic degrees of freedom fractionalises into monopoles, which would account for a mysterious phase transition observed experimentally in spin ice in a magnetic field.

Observation of Dirac monopoles in a synthetic magnetic field
These real-space images provide conclusive and long-awaited experimental evidence of the existence of Dirac monopoles, and provides an unprecedented opportunity to observe and manipulate these quantum mechanical entities in a controlled environment. Expand

A theory of superconductivity in the presence of this gauge flux both in two- and three-dimensional systems is developed and it is found that the superconducting gap has "nodes" as a function of k where the Fermi surface is penetrated by a gauge string. Expand
