a. The material under investigation was a single crystal of Dysprosium Titanate.
This material crystallises in a quite remarkable geometry, the so called pyrochlore-lattice
b. .... show that the magnetic moments inside the material had reorganised into so-called 'spin-spaghetti'
c. As a result, at temperatures from 0.6 to 2 Kelvin,
the strings are visible and have magnetic monopoles at their ends.
d. Providing further confirmation of the existence of monopoles and showing
that they interact in the same way as electric charges.
