The incorporation of geometric frustration and/or low-dimensional motifs within 
magnetic materials can lead to a variety of unusual correlated spin structures 
that are intermediate to the random arrangement of paramagnets and the 
long-range periodic order of (anti)ferromagnets. Characteristic of such partial 
order is the presence of structured diffuse scattering in the neutron magnetic 
scattering function. This talk will discuss various methods for analysing this 
diffuse magnetic scattering, and will illustrate the insight it can provide 
into the unusual magnetic structures of a range of systems, including 
pyrochlore spin-ices [1], elemental Mn [2], garnets [3], and MnO [4]. The talk 
will conclude with a discussion of metal–organic framework chemistry as a route 
to new magnetic materials with unusual topologies [5] for application in 
magnetocaloric solid-state cooling.
