Ice, spin ice and spin liquids lecture April 16, 2013
... It would thus appear that we are done, having explained both significant facts about spin ice. However, this is not the case. First, the nearest-neighbor Ising antiferromagnet is not so simple after all; in fact, it exhibits a divergent correlation length as T ! 0, which cuts off algebraic, dipolar ...

Are pulsars born with a hidden magnetic field? Alejandro Torres-Forné
... an inferred magnetic field significantly lower than the standard values for radio-pulsars (i.e. 1012 G). The main properties of these sources are summarized in Table 1. In all cases, the difference between the characteristic age of the neutron star τc = P/Ṗ and the age of the SNR indicates that the ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
