$\mu$SR Spectroscopy

Muon spin rotation/relaxation ($\mu$SR) spectroscopy is an instrumental technique that utilizes the magnetic moment of a muon, primarily to probe the internal magnetic field distribution of a sample. The technique is extremely sensitive to both static and dynamic magnetism on an atomic scale. In this chapter a brief description of $\mu$SR and how it can be applied to measurements of the vortex state in a type-II superconductor is given.
