Hmmm... I suppose with a crystal of Dysprosium Titanate that crystallises in a quite remarkable geometry, the so called pyrochlore-lattice...... using of neutron scattering, maybe you could show that the magnetic moments inside the material will reorganize into 'spin-spaghetti'. (This name comes from the ordering of the dipoles themselves, such that a network of contorted tubes (strings) develops, through which magnetic flux is transported. These can be made visible by their interaction with the neutrons which themselves carry a magnetic moment. Thus the neutrons scatter as a reciprocal representation of the Strings.)
During the neutron scattering measurements, you could apply a magnetic field to the crystal and thus influence the symmetry and orientation of the strings. Thereby, it may be possible to reduce the density of the string networks and promote the monopole dissociation. As a result, at temperatures from 0.6 to 2 Kelvin, the strings may be visible and have magnetic monopoles at their ends....maybe?
