Magnetism
The neutron's magnetic moment can be used to study the microscopic magnetic properties of materials.

Magnetism is one of the most familiar properties of materials that we come across in our everyday life but it can also be one of the most counterintuitive. From electric motors to computer hard disks, we rely on magnetic materials to underpin much of modern technology. Advances in such technology require new materials and greater understanding of existing ones. Magnetism is also important in quantum mechanics because the quantum interactions between the electrons in a material control its magnetic properties, even at the bulk scale. ISIS neutrons and muons are used to investigate a broad range of topics in magnetism, facilitating discoveries of both theoretical and practical significance.
