Usually, magnetic materials can be understood by imagining them as orderly rows of communicating, atomic-sized bar magnets (or "spins") which organize themselves into a favorable state (e.g. if they choose to be all parallel, the material is magnetized). In a frustrated material, the geometric arrangement of atoms prevents this, and the atomic magnets remain fluctuating. However, they still self-organize (or correlate) locally, with their close neighbors. The size and shape of these regions, which can be measured by neutron scattering, provide strong clues about the frustrated state. Because local correlations are also a property of liquids, these magnets are called spin liquids. Tb3Ga5O12 may host an interesting type of spin liquid in which both magnetic and vibrational fluctuations play a role. We propose to use WISH to search for signs of the associated magnetic correlations.
