Magnetism: Freedom for the poles
Oleg Tchernyshyov1
Abstract
Magnetic poles always come in twos, a north and a south. That received wisdom has not stopped physicists from searching for 'monopoles' in accelerators and cosmic rays. Theory now indicates a better place to look.
Despite some tantalizing clues for their existence from the realms of quantum physics, magnetic monopoles — single magnetic poles without a partner — remain elusive after decades of searching. Do they exist at all in the real world?
- Oleg Tchernyshyov is in the Department of Physics and Astronomy, Johns Hopkins University, 3400 North Charles Street, Baltimore, Maryland 21218, USA.

Magnetic monopoles in spin iceNature Letters to Editor (03 Jan 2008)
Magnetic monopoles have for a long time eluded detection by experiment. Theory now identifies a signature of monopole dynamics that is measurable experimentally, and that has already been seen in magnetic relaxation measurements in a spin-ice material.
