We use chemistry to arrange unusual crystal structures that set up conflicting interactions between magnetic ions in the material. In these compounds i is not possible for a conventional, ordered magnetic arrangement to occur and they are said to be 'frustrated'. Instead, the ions adopt unusual configurations so that they minimise their energy as much as possible; typically freezing with some degree of disorder. Our frustrated materials show an highly unusual form of magnetic ordering, where the long range organisation of the magnetic ions occurs for only a few nanoseconds before disordering and then reordering. These are exceptional as they show a highly ordered array, if viewed quickly enough, but are highly disordered if viewed for a longer period of time and this may give clues the underlying Physics of new ways of organising matter.
