Neutrons as a Probe of Magnetization on Atomic to Mesoscopic Scales

摘要

The neutron is a spin 1/2 particle with a well-specified magnetic dipole moment which interacts with magnetic fields in solids. Because typical neutron wave- lengths are comparable to interatomic distances in solids, the fields that can be probed range from the dipoles of indi- vidual electron sins to those associated with flux lines in superconductors. In this article, we give a brief introduction to the use of magnetic neutron scattering in materials science.
