Resonating valence bonds: a new kind of insulator. Observation of magnetic monopoles in spin ice. Dirac strings and magnetic monopoles in the spin ice Dy2Ti2O7. This paper extracts an experimental value for the charge of a magnetic monopole in spin ice, on the basis of an analogy of the monopole plasma to a classical electrolyte. Measurement of the charge and current of magnetic monopoles in spin ice. Deviations from Ohm's law in weak electrolytes. This paper shows how the density and dynamics of magnetic monopoles can be inferred from the experimental magnetization relaxation rate in spin ice. Signature of magnetic monopole and Dirac string dynamics in spin ice. This theoretical paper proposed that magnetic monopoles are present in spin ice.
