Abstract
NMR and μ sr are powerful local probes of magnetism which often complement neutron studies. This article consists of a brief introduction to those two techniques at a basic level for phD students and reseachers having some knowledge in magnetism but none in resonance techniques. The aim is to provide the basic knowledge of the outcomes and issues of these techniques in order to understand the related litterature.

The great advantage of muons is that they can be implanted in any materials and that the sensitivity of the measurement does not depend neither on the material nor external conditions such as temperature or applied magnetic field
Summary
The first detection of nuclear magnetic resonance (NMR) in a liquid by F. The main research field remains magnetism and superconductivity which fully take advantage of the exquisite sensitivity of the muon to detect small magnetic fields. Both NMR and SR are local probe techniques which means that the nuclei or muon spins are probing the local fields in their close vicinity, typically at the atomic scale. Another specificity of these techniques is that they are sensitive to very low energy excitations, typically in the eV range. This separation may hide the similarity of the two techniques which appears more clearly in chapter 6 dedicated to measurements of spin dynamics where the same formalism applies for both NMR and SR
